Optical Properties of Low Energy Ion Assisted Deposited TiO(2) Films. (9999)

Krishna, M. Ghansyam, Rao, K. Narasimha, Murthy, M. Adinarayana, Mohan, S.

Absorption in TiO(2) films limts their efficiency and stability against high power laser radiation. The optical absorption in single layer TiO(2) films is greatly influenced by deposition parameters...

Properties of Ion Assisted Deposited Titania Films. (9999)

Krishna, M. Ghanashyam, Rao, K. Narasimha, Mohan, S.

Thin films of titanium dioxide have been deposited using ion assisted deposition with oxygen ions in the energy range 100-500 eV and current densities up to 100 micro A/cm(2). It has been observed...

Transient free convection in a fluid saturated porous media with temperature dependent viscosity (1994)

Rao, K Narasimha, Pop, I

The effect of temperature dependent viscosity on the heat transfer rate for a transient free convection in a porous medium adjacent to a vertical flat surface is studied. Solutions are obtained...

Buoyancy-induced flow of non-newtonian fluids in a porous medium past a vertical flat plate with nonuniform surface heat flux (1994)

Mehta, K N, Rao, K Narasimha

Steady buoyancy-induced flow of a non-Newtonian fluid in a porous medium bounded by a vertical flat plate with prescribed variable wall heat flux is investigated analytically by Karman-Pohlhausen...

Dynamic interaction between boundary layer flow and groundwater flow separated by a porous bed (1994)

Mehta, K N, Rao, K Narasimha

This paper examines the problem of dynamic interaction between a steady-state axisymmetric boundary layer flow over a fluid-saturated porous bed and a uniform Darcy flow occurring in the bed. The...
