Flow and Windage Heating in Labyrinth Seals
(2017-11-24)
The ability to quantify leakage flow and windage heating for labyrinth seals with honeycomb lands is critical in understanding gas turbine engine system performance and predicting its component lifes. Variety of labyrinth ...
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 ...
Exploration And Assessment of HCCI Strategies for a Multi-Cylinder Heavy-Duty Diesel Engine
(2017-10-17)
Homogeneous Charge Compression Ignition (HCCI) combustion is an alternative combustion mode in which the fuel is homogeneously mixed with air and is auto-ignited by compression. Due to charge homogeneity, this mode is ...
Effect of Convection and Shrinkage on Solidification and Microstructure Formation
(2017-11-24)
Understanding the fundamental mechanisms of solidification and the relative significance of different parameters governing these mechanisms is of vital importance for controlling the evolution of microstructure during ...
Interaction of Bubbles with Vortical Structures
(2017-09-23)
Bubbly turbulent flows occur in a variety of industrial, naval and geophysical problems. In these flows, the bubbles in the flow interact with turbulence and/or vortical structures present in the continuous phase, resulting ...
Influence of Contact Stresses on Shape Recovery in Sputter Deposited NiTiCu Thin Films
(2017-10-05)
NiTiCu is a shape memory alloy that regains its original shape after large amount of shape changing deformation when heated above a critical temperature called reverse martensitic trans-formation temperature( Af). When ...
Geometric Reasoning with Mesh-based Shape Representation in Product Development
(2017-10-09)
Triangle meshes have become an increasingly popular shape representation. Given the ease of standardization it allows and the proliferation of devices (scanners, range images ) that capture and output shape information as ...
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)
The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ...
