  • Finite Element Analysis in Nanotechnology Research Rameshbabu Chandran
    Chapter Finite Element Analysis in Nanotechnology Research RameshBabu Chandran Abstract The Finite Element Analysis in the field of Nanotechnology is continually contributing to the areas ranging from electronics, micro computing, material science, quantum science, engineering, biotechnology, medicine, aerospace, and environment and in computational nanotechnology. The finite element method (FEM) is widely used for solving problems of traditional fields of engineering and Nano research where experimental analysis is unaffordable. This numerical technique can provide accurate solution to complex engineering problems. Over decades this method has become the noted research area for the mathematicians. The popularity of FEM is due to the advent of computer FEA software such as NASTRAN, ANSYS, ABAQUS, Matlab, OPEN Foam, Simscale and the like. With the development of nanoscience, the researchers found difficulties in spending funds for nano related projects. The FEA has evolved as the affordable methodology and offers solutions to all complicated systems of research. Keywords: nanotechnology, FEM, FEA, research, nanoscience 1. Introduction “To move precisely in nanoworld, you donot succeed by perfecting proven techniques”.- Handelsblat. [1] . As stated, the nano research requires newer methodologies and techniques to be worked out to succeed. The microtechnol- ogy to nanotechnology needs a factor of thousand for size reduction. Different methodologies exist to club cooperation between macro, micro and nano robots and analytical based FEM for static, modal, harmonic and transient analysis of structures. Clubbed with multiparametric optimization and neural networks, FEM had developed as an optimal solution to all complicated problems of engi- neering, science, technology, medicine and research. The “bottom up” technology of late twentieth century promises the use of robotics for micro/nano manipula- tion processing [1].

  • Computational Fluid Dynamics for Biomimetics
    THE CANADIAN SCIENCE FAIR JOURNAL ARTICLE Computational Fluid Dynamics For Biomimetics: Springtails Are Not a Drag! Harini Karthik Age: 16 | Montreal, Quebec Online STEM Fair Regionals Ribbon (2020) | Youth Science Canada Ribbon (2020) Drag is a true annoyance for many industrial sectors around the world. Drag force is produced by the friction of a flowing fluid flowing on the surface that lowers the energy efficiency of the system. This experiment attempts to minimize the drag force by testing theoretical biomimetic coatings. This approach was proven efficient using the digital method known as Computational Fluid Dynamics (CFD) for solving this fluid-flow problem. The morphological structures of different organisms were modeled using software tools such as Salome, OpenFOAM, and ParaView for further comparison. According to the results generated by the simulations, the drag reduced significantly for moderate Reynolds’ Number ranges. This technique can be applied to fabricate hydrophobic coatings to maximize the energy effi- ciency of various systems like solar panels. INTRODUCTION Drag is an invisible resistive force that challenges the performance of various industrial sectors. In the scientific world, drag measures the system’s energy efficiency in reference to the surface topogra- phy and the rate of the flowing fluid. Flat surfaces are observed to cause flow instabilities, thereby increasing the friction (drag). The morphological structures of biological organisms (Tetrodontophora Bielanensis, Rosaceae, and Morpho Peleides) were modeled using software tools such as Salome, OpenFOAM, and ParaView. Computational Fluid Dynamics (CFD) was a digital method that was applied to solve this fluid-flow problem. Results indicated that streamlined surfaces are better at vortex shedding compared to planar surfaces.

M&S can greatly reduce the time and cost it takes to develop new products and thus increasing the manufacturing company's competitiveness. This paper describes the construction of M&S platform based on High Performance Computer (HPC) cloud. High performance Engineering MOdeling & Simulation (HEMOS) is a M&S software developed to support structural analysis and fluid analysis. Developed using open-source software, it supports all M&S processes from pre-processing to analysis and post-processing. HEMOS is developed to simplify shapes, create mesh, and detect contact surfaces at the pre-processing. It uses CalculiX and OpenFOAM, both open-source solvers, to analysis structural and fluid problems without license restrictions at the analysis while OpenGL and Paraview were used to implement post-processing. HEMOS is provided through HEMOS-Cloud which was built based on Xen server with 532 CPU cores and is connected with KISTI’s supercomputer of about 300TF. This HPC Cloud-based modeling and simulation platform that services HEMOS can increase user accessibility and reduce costs.

Welcome to the 2021 Fluids Engineering Division’s (FED) Summer Meeting! While FEDSM 2020 was our first virtual event, I hope FEDSM 2021 is the last virtual FEDSM. FED continues to strive to meet the challenges of disseminating timely technical information by organizing technical conferences and conducting workshops and panel discussions. This year the summer meeting is a FED focused event, and we are collaborating with the ASME Aerospace Engineering Division who sponsors a track at FEDSM 2021. Some recent past collaborations in FEDSM include: FEDSM 2020 with the ASME Heat Transfer Division and the International Conference on Multi- Mini-and Nano Channels, AJK2019 with the Japanese and Korean mechanical engineering societies. In addition, FED also participates annually in the ASME International Mechanical Engineering Congress and Exposition each November. Despite the challenges we all have been facing, FEDSM 2021 is still truly international, which is evident in international participation, including 30 countries spanning five continents with more than 350 presentations. The State-of-the-Art in the world of Fluids Engineering will be presented from industrial, academic, and governmental researchers.
