Summary of the proposed research and expected deliverables Jet noise is one of the primary factors that induces dynamic load on vehicle structures during lift- off of launch vehicle. The high level of vibration produced during lift-off can lead to malfunction of electric/electronic packages, control system components and fatigue failure of light weight structures. Further, the noise specifications in the crew module are also governed by the jet noise. Hence, the transmission of the jet noise is an essential technology to be developed for efficient design of the crew module and associated systems. The jet noise distribution (PSD and spatial correlation) is used as a forcing function to compute the transmitted noise along a structure. Scope of the work: Large Eddy Simulations using either a new developed code or open-source code for an ideally expanded supersonic jet to be carried out and the jet noise results are to be validated. LES simulations for a free jet (Me=2.8, Pe/Pinf=2.4) have to be carried out and the jet noise field (temporal PSD and spatial correlation) has to be characterized in both near and farfield. Development of a simplified model for computing the noise characteristics for this jets at different regions is also encouraged. Deliverables: LES code along with the details of the implementation and jet noise field for the free jet. 11 RESPOND BASKET 2021 VSSC - 002 1. Name of ISRO Centre/Unit Vikram Sarabhai Space Centre, Thiruvananthapuram 2. Title of the research proposal Influence of back pressure perturbations on the unsteady shock wave-boundary layer interaction 3. Name of Co PI from ISRO Centre/Unit Dr. Desikan. SLN 4. Contact Address of Co PI & e-mail id HWTD/ AERONAUTICS Entity Vikram Sarabhai Space Centre, Thiruvananthapuram. e-mail: [email protected] 5. Area of Research Wind Tunnel Studies 6. Summary of the proposed research and expected deliverables The scramjet engine is prone to an undesirable situation so called unstart due to many factors. Such a scenario occurs due to the combustion instability waves produced in the combustion chamber situated downstream of the isolator exit propagate upstream as strong pressure waves or as a normal shock. If the isolator fails to prevent the normal shock wave reaching the intake duct, the intake is prone to unstart. Hence, to understand the dynamics of the normal shock due to the downstream pressure perturbations and its interaction with the boundary layer certainly help for understanding the start/unstart characteristics of an intake. Thus, the study will aid in selection of suitable control devices to prevent unstart event. Scope of the work: As a part of this project, the response of an unsteady shock wave to the various back pressure perturbation frequencies and the nature of unsteady pressure field on its subsequent interaction with the turbulent boundary layer to be briefly studied at various supersonic Mach numbers. The flow physics needs to be captured using unsteady pressure measurements and the time resolved schlieren images. Also, suitable control mechanisms to be proposed in case of unstart events. Deliverables: A complete report with the detailed analysis of the shock wave dynamics and its interaction with the boundary layer in the presence of back pressure fluctuations and suitable control mechanisms shall be submitted. 12 VIKRAM SARABHAI SPACE CENTRE VSSC - 003 1. Name of ISRO Centre/Unit Vikram Sarabhai Space Centre, Thiruvananthapuram 2. Title of the research proposal Data assimilation for fluid dynamics using experimental and computational data 3. Name of Co PI from ISRO Centre/Unit Shri Padmanabha Prasanna Simha 4. Contact Address of Co PI & e-mail id WTDD/WTG, AERONAUTICS Entity, VRC Vikram Sarabhai Space Centre, Thiruvananthapuram. e-mail: [email protected] 5. Area of Research Experimental Fluid Mechanics 6. Summary of the proposed research and expected deliverables Data assimilation is a popular technique used in geophysics, meteorology and oceanography. In several cases highly complex, multi-scale turbulent flow dynamics exist and must be captured. Experimental methods frequently give data in limited numbers due to facility, model and instrumentation limitations. Computational methods are only as good as the dynamical system model and the fidelity of the simulations performed. In such situations, data assimilation can be a valuable tool to mutually integrate experimental data and CFD simulations in order to compensate for the deficiencies in both techniques. The assimilated flow should be able to recover quantities in the experiment which would otherwise be inaccessible or difficult to measure such as pressure, vorticity and Reynolds stresses, by reducing noise and improving resolution. It is also possible to extrapolate the flow beyond the experimental view by solving the equations on a larger domain. CFD results of multiple fidelity levels can also be used as inputs to data assimilation where a DNS/LES performed on a small domain can be assimilated with data. Data assimilation methods available in literature can be reproduced initially. The method formulated must be able to incorporate an arbitrary number of point flow measurements (velocity/pressure) along with the experimental or computational flowfield data. These will be applied to real world problems and attempts to improve the methods of data assimilation must be explored. Scope of the work: 1.
