THE EFFECT OF THERMAL DISPERSION ON UNSTEADY MHD CONVECTIVE HEAT TRANSFER THROUGH VERTICAL POROUS
The influence of thermal dispersion on unsteady two-dimensional laminar flow is presented. A viscous incompressible conducting fluid in the vicinity of a semi infinite vertical porous through a moving plate in the presence of a magnetic fluid is studied. A cod (FORTRAN) was constructed for numerical computations for the velocity and temperature for various values of the affected parameters are carried out.

COSMOLOGICAL MODEL WITH ULTRARELATIVISTIC IDEAL GAS USING GRAVITATIONAL AND THERMO–MECHANICAL HAMILTONIAM FORMULATION
A brief review of the Hamiltonian theory of self gravitating perfect fluid, which has been established by Kijowski et al (1990), has been discussed in this work. The formulation of the spherically symmetric cosmological problem has been derived. The most general 3-dimensional metric in the case of spherically symmetric space-time has been considered. In addition, the parameters which govern the dynamics have been fixed. The dynamical equations have been derived. The problem of homogeneous Universe has been considered for the Ultrarelativistic ideal gas. The dynamical equations have been derived. Three analytical solutions have been obtained.
