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 ...
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 ...
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, ...
Microgravity Flow Transients in the Context of On-Board Propellant Gauging
(2018-02-15)
It is well known that surface tension of a liquid has a decisive role in flow dynamics and the eventual equilibrium state, especially in confined flows under low gravity conditions and also in free surface flows. One such ...
Cyclic Pursuit : Variants and Applications
(2018-02-11)
The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled ...
LES Study Of Free Jets And Jets Impinging On Cuboidal Cavity
(2016-09-15)
Numerical solutions based on explicit filtered LES for computing turbulent flow field, of free round jets and impinging round jet on cuboidal cavities, are presented and discussed in this dissertation work. One-parameter ...
Computational Studies On Certain Problems Of Combustion Instability In Solid Propellants
(Indian Institute of Science, 2006-11-17)
This thesis presents the results and analyses of computational studies on certain problems of combustion instability in solid propellants. Specifically, effects of relaxing certain assumptions made in previous models of ...
