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 ... -
Linear Stability Models for Reacting Mixing Layers
(2018-03-12)We develop a physics-based reduced-order model of the aero-acoustic sound sources in reacting mixing layers as a method for fast and accurate predictions of the radiated sound. Instabilities in low-speed mixing layers are ... -
Liquid Jet in Swirling Cross Flow
Liquid jets in cross flows (JICF) have been an important part of spray research in the last few decades owing to the wide spectrum of applications ranging from agricultural sprays to aircraft gas turbine engines. However, ... -
Longitudinal Acceleration-based Variable Speed Bio-inspired Guidance Law
Most analyses of existing interceptor guidance laws assume the interceptor speed to be constant, which simplifies mathematical analysis and enhances predictability in interception characteristics. In reality, this is not ... -
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 ... -
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. ... -
Matrix cracking in polymer matrix composites under static and fatigue loading
Matrix cracking is the first and most dominant mode of damage in polymer matrix composite (PMC) laminates resulting in significant stiffness degradation under static and fatigue loading. Matrix crack evolution and its ... -
Measurement Of Static Pressure Over Bodies In Hypersonic Shock Tunnel Using MEMS-Based Pressure Sensor Array
(2013-10-08)Hypersonic flow is both fascinating and intriguing mainly because of presence of strong entropy and viscous interactions in the flow field. Notwithstanding the tremendous advancements in numerical modeling in the last ... -
Mechanical Characterization of Carbon Nanotubes and Nanocomposites
(2018-08-14)Measurement of all the mechanical properties of carbon nanotubes is extremely difficult because of its small size. In the present work, all the five transverse isotropic properties of single wall carbon nanotubes (SWCNTs) ... -
Mechanics of Martensitic Phase transformation in shape memory alloys Experiments and modelling
Thermally activated NiTi based Shape Memory Alloys (SMAs) are of tremendous practical interest as actuators in varied engineering applications owing to its characteristic Martensitic Phase Transformation (MPT). The MPT in ... -
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 ... -
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 ... -
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 ... -
