LU-SGS Implicit Scheme For A Mesh-Less Euler Solver
(2014-10-10)Least Square Kinetic Upwind Method (LSKUM) belongs to the class of mesh-less method that solves compressible Euler equations of gas dynamics. LSKUM is kinetic theory based upwind scheme that operates on any cloud of points. ... -
Micro-Blast Waves
(2014-09-02)The near field blast–wave propagation dynamics has been a subject of intense research in recent past. Since experiments on a large scale are difficult to carry out, focus has been directed towards recreating these blast ... -
Novel Finite Element Formulations For Dynamics Of Acoustic Fluids
(2013-05-02)Fluid-structure interaction (FSI) as the name suggests, is the study of dynamic interaction of both fluid and structure motions. Fluid-structure interaction exists in almost all engineering and science fields. Moreover, ... -
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 ... -
Optimal Control Of Numerical Dissipation In Modified KFVS (m-KFVS) Using Discrete Adjoint Method
(2010-06-04)The kinetic schemes, also known as Boltzmann schemes are based on the moment-method-strategy, where an upwind scheme is first developed at the Boltzmann level and after taking suitable moments we arrive at an upwind scheme ... -
Optimal Trajectory Planning for Fixed-Wing Miniature Air Vehicles
(2018-04-02)Applications such as urban surveillance, search and rescue, agricultural applications, military applications, etc., require miniature air vehicles (MAVs) to fly for a long time. But they have restricted flight duration due ... -
Residual Error Estimation And Adaptive Algorithms For Fluid Flows
(2011-03-16)The thesis deals with the development of a new residual error estimator and adaptive algorithms based on the error estimator for steady and unsteady fluid flows in a finite volume framework. The aposteriori residual error ... -
Shape Optimization Using A Meshless Flow Solver And Modern Optimization Techniques
(2009-03-17)The development of a shape optimization solver using the existing Computational Fluid Dynamics (CFD) codes is taken up as topic of research in this thesis. A shape optimizer was initially developed based on Genetic ... -
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 ... -
Study Of Stall Flutter Of An Isolated Blade In A Low Reynolds Number Incompressible Flow
(2015-07-08)Highly-loaded turbomachine blades can stall under off-design conditions. In this regime, the flow can separate close to the leading edge of the blade in a periodic manner that can lead to blade vibrations, commonly referred ... -
Turbulent Near Wake Behind An Infinitely Yawed Flat Plate
(Indian Institute of Science, 2005-09-20)Near wake is the region of wake flow just behind the trailing edge of the body where the flow is strongly influenced by the upstream flow conditions and also perhaps by the characteristics of the body. The present work ... -
Vibration And Impact Induced Sound
(2010-10-22)Sound generated by impacting structures is of considerable importance in noise control. Sound is generated by a vibrating structure by inducing pressure fluctuations in the surrounding medium. Impact induced noise is the ... -
Wave Propagation In Hyperelastic Waveguides
(2014-06-20)The analysis of wave propagation in hyperelastic waveguides has significant applications in various branches of engineering like Non-Destructive Testing and Evaluation, impact analysis, material characterization and damage ... -
Wing in Ground Effect
(2017-12-01)The thesis presents a two pronged approach for predicting aerodynamics of air- foils/wings in the vicinity of the ground. The first approach is effectively a model for ground effect studies, employing an inexpensive Discrete ...
