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 ...
Analysis Of Solar Pumped Chemical Oxygen Iodine Laser
(Indian Institute of Science, 2006-10-11)
Chemical Oxygen Iodine Laser(COIL) is an electronic transition high energy chemical laser having a wavelength of 1.315 /mi. This is the first chemical laser to operate on an electronic rather than a rotational or vibrational ...
A Methodology To Recover Unstable Aircraft From Post Stall Regimes: Design And Analysis
(Indian Institute of Science, 2006-07-26)
This thesis deals with high angle of attack behaviour of a generic delta wing model aircraft. A high angle of attack wind tunnel database has been generated for this aircraft and based upon the bifurcation analysis of the ...
Application Of Controlled Random Search Optimization Technique In MMLE With Process Noise
(Indian Institute of Science, 2006-08-08)
Generally in most of the applications of estimation theory using the Method of Maximum Likelihood Estimation (MMLE) to dynamical systems one deals with a situation where only the measurement noise alone is present. However ...
Implicit Least Squares Kinetic Upwind Method (LSKUM) And Implicit LSKUM Based On Entropy Variables (q-LSKUM)
(Indian Institute of Science, 2006-10-12)
With increasing demand for computational solutions of fluid dynamical problems, researchers around the world are working on the development of highly robust numerical schemes capable of solving flow problems around complex ...
A Numerical Study On Absolute Instability Of Low Density Jets
(Indian Institute of Science, 2006-07-20)
A spectacular instability has been observed in low density round jets when the density ratio of jet fluid to ambient fluid falls below a threshold of approximately 0.6. This phenomenon has been observed in non-buoyant jets ...
Low Reynolds Number Airfoil Aerodynamics
(Indian Institute of Science, 2006-07-21)
In this thesis we describe the development of Reynolds- averaged Navier Stokes code for the flow past two- dimensional configuration. Particularly, emphasis has been laid on the study of low Reynolds number airfoil ...
A High-Resolution Procedure For Euler And Navier-Stokes Computations On Unstructured Grids
(Indian Institute of Science, 2006-07-20)
A finite-volume procedure, comprising a gradient-reconstruction technique and a multidimensional limiter, has been proposed for upwind algorithms on unstructured grids. The high-resolution strategy, with its inherent ...
Experimental And Theoretical Studies On Jet Acoustics
(Indian Institute of Science, 2006-12-14)
A systematic research on aeroacoustics conducted around the world for the last few decades has revealed various inherent characteristics of the jet noise radiation. However, a lot more needs to be done for the theoretical ...
Transport Phenomena In Laser Surface Alloying: A Numerical Investigation
(Indian Institute of Science, 2006-08-24)
A comprehensive, transient three-dimensional model of a single-pass laser surface alloying process has been developed and used to examine the heat, momentum and species transport phenomena. A numerical study is performed ...
