Effect of Favourable Pressure Gradient on Turbulence in Boundary Layers
(2018-07-16)This thesis explores the effects of favourable pressure gradient on the structure of turbulent boundary layers (TBL). In this context, the structure of three types of boundary layers namely a zero-pressure-gradient ... -
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 ... -
Linear Instability Of Laterally Strained Constant Pressure Boundary Layer Flows
(Indian Institute of Science, 2007-03-26)The linear instability of laterally diverging/converging flows is an important aspect towards understanding the laminar-transition process in many viscous flows. In this work the linear instability of constant pressure ... -
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 ... -
On Three Dimensional High Lift Flow Computations
(2018-02-18)Computing 3D high lift flows has been a challenge to the CFD community because of three important reasons: complex physics, complex geometries and large computational requirements. In the recent years, considerable progress ... -
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 ...
