Abstract: The objective of this mini symposium is to develop a mathematical model and to investigate analytically or numerically and systematically the study of flow problems; free, forced and mixed convection heat and mass transfer arises in fluid mechanics. Study of such type of problems in fluid mechanics has received enormous attention of many researchers in industrial applications, scientific and engineering fields. The subject is multidisciplinary and completely encircles the main views of applied mathematics to areas like soil physics, hydrogeology, petroleum industry, filtration of solids from liquids, chemical engineering, biological systems, oil reservoir modelling, food processing, casting and welding, manufacturing processes, the dispersion of pollutants into environment, storage of nuclear waste, power plant stream lines, bio mechanical, polymerization, fluid mechanics, filters, chemical, mechanical, paper and cloth industry, geophysics, chemistry etc.

The following are the abstracts proposed for the mini symposia:

A numerical solution for the free convective, unsteady, laminar convective heat and mass transfer in a MHD viscoelastic fluid along a semi-infinite vertical plate with Soret and Dufour effects is presented. The Walters-B liquid model is employed to simulate medical creams and other rheological liquids encountered in biotechnology and chemical engineering. This rheological model introduces supplementary terms into the momentum conservation equation. The dimensionless unsteady, coupled, and non-linear partial differential conservation equations for the boundary layer regime are solved by an efficient, accurate and unconditionally stable finite difference scheme of the Crank-Nicolson type.

The aim of this study is to present chemical reaction and thermophoretic effects on MHD mixed convective incompressible flow, viscous and electrically conducting fluid over a radiate isothermal inclined plate embedded in a porous medium in the presence of heat source/sink.

We analyzed the effects of thermal radiation, viscous dissipation and magneticfield on boundary layer flow of a nanofluid past a nonlinear permeable stretching/shrinking sheet.

In this problem the flow of a Viscoelastic fluid due to a linearly and quadraticaly stretching sheet and heat transfer characteristics using variable thermal conductivity is studied in the presence of a non uniform heat source/sink. The thermal conductivity is assumed to vary as a liner function of temperature. The similarity transformation is used to convert the governing partial differential equations of flow and heat transfer into a ordinary differential equations. Shooting method is used to obtain the numerical solution for the resulting boundary value problem. The effects of Chandrashekar Number, Prandltl Number, Non-Uniform heat source/sink parameters and Variable Thermal Conductivity parameter on the dynamics are shown graphically in several plots.

In this paper, a multi grid analysis of the effect of surface roughness in hydrodynamic lubrication of a porous journal bearing with a heterogeneous slip/no-slip surface is studied. In the traditional lubrication theory, it has been assumed that all the bearing surfaces are smooth but it is unrealistic study for the bearing with small film thickness.

This study reports a numerical investigation of the convective flow and heat transfer in a square porous cavity with partially active thermal walls. Five different heating and cooling zones are considered along the vertical walls
