Edge Effect of Semi-Infinite Rectangular Posts on Impacting Drops
(2018-05-30)The inhibiting effect of a sharp edge on liquid spreading is well observed during drop interaction with textured surfaces. On groove-textured solid surfaces comprising unidirectional parallel grooves, the edge effect of ... -
Effect of a Mesh on Boundary Layer Transition Induced by Free-stream Turbulence and an Isolated Roughness Element
(2018-06-23)A high level of free-stream turbulence and surface roughness are known to cause breakdown of an otherwise stable laminar flow. In transition induced by free-stream turbulence, streaks are formed due to the lift-up effect ... -
Effect Of Cross-sectional Nonlinearities On Anisotropic Strip-based Mechanisms
(2013-05-28)The goal of this work is to develop and demonstrate a comprehensive analysis of single and multi-body composite strip-beam systems using an asymptotically-correct geometrically nonlinear theory. The comprehensiveness ... -
The Effect Of Energy Deposition In Hypersonic Blunt Body Flow Field
(2010-09-23)A body exposed to hypersonic flow is subjected to extremely high wall heating rates, owing to the conversion of the kinetic energy of the oncoming flow into heat through the formation of shock waves and viscous dissipation ... -
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 ... -
Effective Property Estimation of Carbon Composites using Micromechanical Modeling
(2018-02-28)In recent times, composite materials have gained mainstay acceptance as a structural material of choice due to their tailorability and improved thermal, specific strength/stiffness and durability performance. Carbon-Carbon ... -
Efficient Trim In Helicopter Aeroelastic Analysis
(2011-04-06)Helicopter aeroelastic analysis is highly complex and multidisciplinary in nature; the flexibility of main rotor blades is coupled with aerodynamics, dynamics and control systems. A key component of an aeroelastic analysis ... -
Electric Field-Guided Alignment of Carbon Nanotubes in Polymer Matrix Composites for Structural Applications
Carbon nanotubes (CNTs) have been extensively researched for diverse applications in recent years. In the present work, the use of low frequency non-uniform alternating electric fields to manipulate the alignment behavior ... -
Energy Separation And Lox Separation Studies In Vortex Tubes
(2014-11-24)Vortex Tube (VT) is a simple device having no moving mechanical parts, in which compressed gas at high pressure is injected through one or more tangential nozzles into a vortex chamber resulting in the separation of the ... -
Evaluation of Hygrothermal Ageing In Cfrp Composite Material: A Study Using Non-destructive Techniques
Advanced composite materials are replacing conventional metals/alloys in aerospace industries due to their excellent strength and stiffness-to-density ratio as well as some other better physical and mechanical properties ... -
Evolutionary Optimization For Vibration Analysis And Control
(2014-03-03)Problems in the control and identification of structural dynamic systems can lead to multimodal optimization problems, which are difficult to solve using classical gradient based methods. In this work, optimization problems ... -
Experimental Analysis of Shock Stand off Distance over Spherical Bodies in Hypersonic Flows
(2018-07-18)One of the characteristics of the high speed ows over blunt bodies is the detached shock formed in front of the body. The distance of the shock from the stagnation point measured along the stagnation streamline is termed ... -
Experimental And Computational Investigations Of Underexpanded Jets From Elliptical Sonic Nozzles
(Indian Institute of Science, 2005-10-25)Three dimensional nozzles and jet flows have attracted the attention of many researchers due to their potential application to many practical devices. Rectangular nozzles are considered for short/vertical take off and ... -
