Analysis of Unsteady Incompressible Potential Flow Over a Swimming Slender Fish and a Swept Wing Tail
(2018-05-16)
This thesis deals with computing the pressure distribution around a swimming slender fish
and the thrust generated by its flapping motion. The body of the fish is modeled as a missile like slender body to which a tail is ...
2D Compressible Viscous Flow Computations Using Acoustic Flux Vector Splitting (AFVS) Scheme
(Indian Institute of Science, 2007-05-07)
The present work deals with the extension of Acoustic Flux Vector Splitting (AFVS) scheme for the Compressible Viscous flow computations. Accurate viscous flow computations require much finer grids with adequate clustering ...
Wave Transmission Characteristics in Honeycomb Sandwich Structures using the Spectral Finite Element Method
(2017-12-12)
Wave propagation is a phenomenon resulting from high transient loadings where the duration of the load is in µ seconds range. In aerospace and space craft industries it is important to gain knowledge about the high frequency ...
Molecular Simulation of Anisotropic Stress and Structure in polymers
(2018-02-15)
This dissertation presents a numerical study using molecular dynamic simulations
that interrogates the polymer structure as it is strained continuously in time and correlates it with the stress developed in it. We investigate ...
Shocks, Shock-Boundary Layer Interaction, And Transonic Flutter
(2017-09-27)
Transonic utter is an aeroelastic instability characterized by part-chord shocks over an airfoil and single mode oscillations leading to a drop in the utter boundary. We present a numerical study that examines the influence ...
Multi-Agent Positional Consensus Under Various Information Paradigms
(2017-02-22)
This thesis addresses the problem of positional consensus of multi-agent systems. A positional consensus is achieved when the agents converge to a point. Some applications of this class of problem is in mid-air refueling ...
Large Eddy Simulation of Free and Impinging Subsonic Jets and their Sound Fields
(2018-02-27)
Evaluating aerodynamic noise from aircraft engines is a design stage process, so that it conform to regulations at airports. Aerodynamic noise is also a principal source of structural vibration and internal noise in ...
Experimental and Computational Studies on Deflagration-to-Detonation Transition and its Effect on the Performance of PDE
(2018-02-26)
This thesis is concerned with experimental and computational studies on pulse detonation engine (PDE) that has been envisioned as a new concept engine. These engines use the high pressure generated by detonation wave for ...
Turbulence Modeling for Predicting Flow Separation in Rocket Nozzles
(2018-01-30)
Convergent-Divergent (C-D) nozzles are used in rocket engines to produce thrust as a reaction to the acceleration of hot combustion chamber gases in the opposite direction. To maximize the engine performance at high ...
Modeling and Simulation of Biomolecular Flow in Microchannel
(2018-01-01)
Microfluidics deals with the behavior, control and manipulation of fluids which are confined at micrometer length scale. It has important application in lab-on-a chip technology, micro-propulsion, additive manufacturing, ...
