Power Loss Minimization for Drag Reduction and Self-Propulsion using Surface Mass Transpiration
(2017-11-29)
The remarkable efficacy with which normal surface mass transpiration (blowing and suction) alters a given base flow to achieve a desired predefined objective has motivated several investigations on drag reduction, ...
Viscous Vortex Method Simulations of Stall Flutter of an Isolated Airfoil at Low Reynolds Numbers
(2017-11-27)
The flow field and forces on an isolated oscillating NACA 0012 airfoil in a uniform flow is studied using viscous vortex particle method. The simulations are carried out at very low chord (c) based ...
A Numerical Implementation of an Artery Model Using Hybrid Fem
(2017-12-07)
The goal of this thesis is to develop a hybrid _nite element formulation to carry out stress analysis of arteries. To the best of our knowledge, a hybrid _nite element impel mentation of the Holzapfel-Ogden artery model ...
Experimental And Numerical Studies On Flame Stability And Optimization Of A Compact Trapped Vortex Combustor
(2013-03-27)
A new Trapped Vortex Combustor (TVC) concept has been studied for applications such as those in Unmanned Aerial Vehicles (UAVs) as it offers potential for superior flame stability and low pressure loss. Flame stability is ...
Crack Tip Fields And Mechanisms Of Fracture In Ductile FCC Single Crystals
(2015-01-07)
An understanding of crack tip fields and fracture mechanisms in single crystals can help in developing better polycrystalline alloys and manufacturing processes. To this end, the effects of loading rate, material inertia ...
Multi-Phase Modeling Of Microporosity And Microstructures During Solidification Of Aluminum Alloys
(2014-04-23)
Manufacturing of light-weight materials is associated with several types of casting defects during solidification. Porosity defects are common, especially in aluminum and its alloys, which initiate crack propagation and ...
Studies On Friction Stir Welding Of Precipitation Hardenable Aluminium Alloys
(2010-06-10)
Friction Stir Welding (FSW) is an emerging solid state welding process. It has been a proven method for welding high strength aluminium alloys which were previously not recommended for conventional fusion welding. Since ...
Single-Phase And Multi-Phase Convection During Solidification Of Non-eutectic Binary Solutions
(2014-10-20)
During solidification of non-eutectic alloys, non-isothermal phase change causes dendritic growth of solid front with liquid phase entrapped within the dendritic network producing the mushy region. Solidification causes ...
Studies On Automization And Sprays Of Plant Oil Biofuels Using Laser-Based Diagnostics
(2014-12-12)
Atomization characteristics of liquid fuel sprays control combustion efficiency and emissions in engines. The present work is motivated by the need to study the atomization and spray structure of vegetable oil biofuels for ...
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 ...
