Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)
The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ...
A Prestress Based Approach To Rotor whirl
(2010-06-02)
Rotordynamics is an important area in mechanical engineering. Many machines contain rotating parts. It is well known that rotating components can develop large amplitude lateral vibrations near certain speeds called critical ...
A Study Of Four Nonlinear Systems With Parametric Forcing
(2010-06-01)
This thesis considers four nonlinear systems with parametric forcing.
The first problem involves an inverted pendulum with asymmetric elastic restraints subjected to harmonic vertical base excitation. On linearizing ...
New Solution Methods For Fractional Order Systems
(2010-09-24)
This thesis deals with developing Galerkin based solution strategies for several important classes of differential equations involving derivatives and integrals of various fractional orders. Fractional order calculus finds ...
Transfer Layer Formation And Friction In Extrusion Of Aluminum : An Experimental Study Using A High Temperature Vacuum Based Pin-On-Disc Machine
(2010-09-21)
Hot extrusion of aluminum is widely practiced in industries for economic production of structural components. The surface finish and tolerance of the extruded components, both from design and aesthetic requirement, are ...
