This Fluidic Device is a passive safety equipment and it is installed at the bottom of the inner space of the SIT. During the past two years, a scale model test to obtain the required flow characteristics of the device under the KNGR specific conditions has been performed using the experience and existing facility of AEA Technology(UK) with appropriate modifications. The performance verification test is to be performed this year to obtain the optimum characteristics and design data of full size Fluidic Device. This report summarizes the results of the model test. The purpose of the model test was to check the feasibility of developing the device and to produce a generic flow characteristic data. The test was performed in approximately 1/7 scale in terms of flow rate with full height and pressure. This report presents the details of system performance requirements for the device, design procedure for the Fluidic Device to be used, test facility and test method. The time dependent flow, pressure and Euler number are presented as characteristic curves and the most stable and the most effective flow control characteristic parameters were recommended through the evaluation. A method to predict the size of the Fluidic Device is presented. And a sizing algorithm, which can be used to conveniently determine the major geometric data of the device for various operating conditions, and a FORTRAN program to produce the prediction of performance curves have been developed. The conditions of this test are very specific, that is, the fluid is high flow water with a very small pressure difference between supply and control port. Therefore, almost no empirical test data is available. Consequently, the test results will be utilized as reference for the future development of full scale of Fluidic Device. - II - 2 # Fluidic Device*] 7^ 3 *1I 1 1 ^ 2) 3 4 2 ^ Vortex Valve*! ^-^ 3 4 3 ^ Vortex Valve*] ^-^^-^ 5 *11 4 ^ Vortex Valve*! -§~§-W 7 3 ^ Fluidic Device 71^2 16 4 l ^ ^^-fi-^i 16 4 2 ^ SIT Tank ^-^ ^^ 2.*i 18 *\] 3 ^ S^M^ ^«1*] ^-fi- ^4^^ 19 4 # S.<i -y^-g- Fluidic Device ^Tfl 20 ^1 1 ^ Fluidic Device Insert #1 21 fl 2 ^ Fluidic Device Insert #2 31 37 1 ^ Test Loop 37 2 ^ #*1 ^-^ 7171 gl 7fl^7l7l 42 y 6^ ^^ o^ 51 4 1 ^ Reference Parameters ^ ^^^.^i 51 ^1 2 ^ ^^ ^*> 53 7 # ^^^^ 55 4 11 ^^2:^ 55 ^1 2 ^ Processing of Data 56 - iii - 3 ^ -iM^f 3g7} 61 8 # Fluidic Device 'gTfl*!^ 67 ff 1 1 Fluidic Device^] -g^l 67 69 71 73 - iv - s. i s.^. ^^-ini^ ^g. -g^tH* 19 .5. 2 Pressure-Flow Characteristics for Oil Choke Valve 1 22 S 3 Pressure-Flow Characteristics for Oil Choke Valve 2 22 I£ 4 Pressure-Flow Characteristics for Oil Choke Valve 3 23 3£ 5 Pressure-Flow Characteristics for Oil Choke Valve 4 23 i£ 6 Reference Valve Designs 24 S 7 Supply Flow at Valve Open Versus Control Port Size 24 S 8 Summary of Data from Oil Choke Valve Work 25 -S 9 Comparison of Valve Dimension Ratios 26 S 10 Insert #2 W*l Vortex Valve^I tj|*> ^ Z%O}B\ 33 S 11 Valve Opening(%) vs Flow Resistance 52 S 12 i^^i H]JSL ^ 55 S 13 ^olW <*^ ^JSL »§a-^^ ^4^ &.<$ 63 S 14 il^otf A}-g4l |H«] j*& ^^]^ 65 S 15 ^«.5] ^A ^-^^^ ^.^ 66 - v - en 1 Vortex Valves ^ (7fl\|.£) 4 2 Vortex ValveSj -^3-^d 5 3 Vortex Diode^I *HHiel 7 4 Vortex Diode ^S^l *}-%• ^} 8 5 4U*}.3.6fl-M Diode7} Reverse Flow Restrictor^. -§--§-S <Hl 9 6 Vortex Amplifier-^ 4^-tls] 10 7 Globe-box Ventilation Control 10 8 ^^^ Vortex Amplifier^} ^%-^-^d 11 9 SIR Primary Circuit Flow Paths 12 10 Principles of Mitsubishi Advanced Accumulator 13 11 Schematic of Fluid Flow in PIUS-BWR Reactor Vessel 14 12 aMM^l-S.

This dissertation focuses on understanding molecular transport through a membrane platform consisting of open ended CNTs with ~ 7 nm core diameter and ~ 1010 CNTs/cm2 encapsulated in an inert polymer matrix. While ionic diffusion through the membrane is close to bulk diffusion expectations, gases and liquids were respectively observed to be transported ~ 10 times faster than Knudsen diffusion and ~ 10000-100000 times faster than hydrodynamic flow predictions.

Newkome Committee Member Date Dr. Purushottam Gujrati Committee Member Dr. Jutta Luettmer-Strathmann ii ABSTRACT The main objective of this dissertation is synthesis of carbon nanotube (CNT) based superhydrophobic materials. The materials were designed such that electrical and mechanical properties of CNTs could be combined with superhydrophobicity to create materials with unique properties, such as self-cleaning adhesives, miniature floatation devices, ice-repellant coatings, and coatings for heat transfer furnaces. The coatings were divided into two broad categories based on CNT structure: Vertically aligned CNT arrays (VA coatings) and mesh-like (non-aligned) carbon nanotube arrays (NA coatings). VA coatings were used to create self-cleaning adhesives and flexible field emission devices. Coatings with self cleaning property along with high adhesiveness were inspired from structure found on gecko foot. Gecko foot is covered with thousands of microscopic hairs called setae; these setae are further divided into hundreds of nanometer sized hairs called spatulas. When gecko presses its foot against any surface, these hairs bend and conform to the topology of the surface resulting into very large area of contact.

  • Nanofluidics in Carbon Nanotubes
    Nanofluidics in carbon nanotubes Extremely high aspect ratios, molecularly smooth hydrophobic graphitic walls, and nanoscale inner diameters of carbon nanotubes give rise to the unique phenomenon of ultra-efficient transport of water and gas through these ultra-narrow molecular pipes. Water and gas molecules move through nanotube pores orders of magnitude faster than through other pores of comparable size. The proposed water transport mechanism has a distinct similarity to the transport mechanisms of biological ion channels. Molecular dynamics simulations and experimental measurements of water transport underscore the importance of nanotube structure in enabling ultra-efficient transport through the pore.

  • 3D Printed Lab-On-A-Chip Platform for Chemical Stimulation and Parallel Analysis of Ion Channel Function
    micromachines Article 3D Printed Lab-on-a-Chip Platform for Chemical Stimulation and Parallel Analysis of Ion Channel Function Daniel Aschenbrenner, Oliver Friedrich and Daniel F. Gilbert * Institute of Medical Biotechnology, Friedrich-Alexander-Universität Erlangen-Nürnberg, 91052 Erlangen, Germany * Correspondence: [email protected] Received: 16 July 2019; Accepted: 16 August 2019; Published: 19 August 2019 Abstract: Functional imaging has been a widely established method for the assessment of ion channel function in vitro. Conventional infrastructure used for in vitro functional analysis of ion channels is typically proprietary, non-customizable, expensive, and requires a high level of skill to use and maintain. 3D desktop printing, which is employed in the rapid prototyping field, allows for quick engineering of alternatives to conventional imaging infrastructure that are customizable, low cost, and user friendly. Here, we describe an ultra-low-cost microfluidic lab-on-a-chip (LOC) device manufactured using acrylonitrile butadiene styrene (ABS) for in vitro functional imaging of ion channels that can quickly and easily be reconstructed using three-dimensional (3D) desktop printing. The device is light weight (<5 g), small (20 mm 49 mm), and extremely low cost (<EUR 1). × We simulate fluidics within the printed channels and assess the suitability of the engineered chamber to generate homogeneous mixtures during solution exchange. We demonstrate the usability of the 3D printed microfluidic device in a case study using Fluo-4-loaded human embryonal kidney-derived (HEK293) cells, recombinantly expressing the capsaicin receptor, transient receptor potential vanilloid receptor type 1 (TRPV1), as a model system. In the case study, we confirm its applicability to solution exchange for chemical stimulation and parallel functional time-lapse fluorescence microscopy-based calcium imaging.

  • DNA Assembly in 3D Printed Fluidics
    DNA Assembly in 3D Printed Fluidics William G. Patrick, Alec A. K. Nielsen, Steven J. Keating, Taylor J. Levy, Che­Wei Wang, Jaime J. Rivera, Octavio Mondragón­Palomino, Peter A. Carr, Christopher A. Voigt, Neri Oxman, David S. Kong Published: December 30, 2015 DOI: 10.1371/journal.pone.0143636 Abstract The process of connecting genetic parts—DNA assembly—is a foundational technology for synthetic biology. Microfluidics present an attractive solution for minimizing use of costly reagents, enabling multiplexed reactions, and automating protocols by integrating multiple protocol steps. However, microfluidics fabrication and operation can be expensive and requires expertise, limiting access to the technology. With advances in commodity digital fabrication tools, it is now possible to directly print fluidic devices and supporting hardware. 3D printed micro­ and millifluidic devices are inexpensive, easy to make and quick to produce. We demonstrate Golden Gate DNA assembly in 3D­printed fluidics with reaction volumes as small as 490 nL, channel widths as fine as 220 microns, and per unit part costs ranging from $0.61 to $5.71. A 3D­printed syringe pump with an accompanying programmable software interface was designed and fabricated to operate the devices. Quick turnaround and inexpensive materials allowed for rapid exploration of device parameters, demonstrating a manufacturing paradigm for designing and fabricating hardware for synthetic biology.
