Abstract Details

2003, Doctor of Philosophy, Ohio State University, Mechanical Engineering.
Flow and heat transfer inside non-isothermal, incompressible, flat and inclined squeezed thin films are analyzed in this study. Analytical solutions for the flow, temperature distribution and heat transfer under different physical constraints are obtained. For an oscillatory squeezed thin films, the influence of the thermal squeezing parameter, Eckert number, pressure gradient inside the thin film, internal pressure pulsations, the stiffness of the supporting seal, presence of suspended ultrafine particles in the fluid and the motion characteristics of the oscillating boundary of a thin film are determined on the flow and heat transfer process inside thin films. This study is extended to consider flow inertia, hydromagnetic and buoyancy effects on the flow and heat transfer inside oscillatory squeezed thin films. Also, flow and heat transfer is considered in thin films having the boundary squeezing effects caused by the fluctuation in the applied thermal load. The leakage from thin films and the possibility of fluid slip at the boundaries are investigated on the flow and heat transfer inside squeezed thin films. The present work plays an important role in modeling flow and heat transfer disturbances inside thin film fluidic cells and generates some remedies that can reduce the effects of these disturbances.
