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 ... -
Effect of Interface Roughness on Mechanical Strength of Adhesively Bonded CFRP Joints- Experimental and Numerical Studies
Composite materials are well known for their superior properties such as specific strength, specific modulus, tailor-ability in different directions, fatigue resistance, durability, low weight, and low thermal expansion. ... -
Effect of Laser Shock Peening on Residual Stress and Mechanical behaviour of Aluminium alloy AA2219 Friction Stir Weld
The Aluminium alloy AA2219 is a precipitation-hardenable wrought alloy with copper as the major alloying element. Large-volume propellant tanks of space launch vehicles are manufactured by joining AA2219 alloy through ... -
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 ... -
