Abstract :In this paper Laminar MHD flow in the entrance region of a plane channel with dissipation under the influence of transverse magnetic field. The motion of laminar conducting fluid between two parallel plates is considered. The channel has height of 2a and a width of d. A rectangular coordinate system is placed on channel with the origin at the center of channel at the left hand edge. The flow problem is described by means of partial differential equations and solutions are obtained by the use of a finite difference technique. The velocity, temperature and pressure profiles are shown in graphs and their behaviour is discussed for the different values of magnetic field parameter M and Eckert Number Ek for fixed Prandtl Number Pr.

Abstract :In this paper a mathematical analysis of effect of couple stresses on magneto hydrodynamic (MHD) flow past a parallel plate channel of viscous, incompressible and electrically conducting fluid in the presence of porous medium has been studied. An exact solution of the dimensionless governing equations has been obtained by using method of perturbation technique. The effects on velocity, discharge between the plates and wall shear are studied for different parameters like Hartmann number, Reynolds number, pulsation, time, porosity parameter, pulsation frequency and reported graphically to show the interesting aspect of the solution.

Abstract :The present model discusses the drug distribution in the layers of human dermal parts. We have considered tissue absorption rate of drug is decreasing function of drug concentration, also considered linear shape functions for approximating element wise approximate solution by Finite Element Method (FEM).In this method each region is referred to as an element and the process of subdividing a domain into a finite number of elements is referred to as discretization. Elements are connected at specific points, called nodes, and the assembly process requires that the solution be continuous along common boundaries of adjacent elements. MATLAB Software used for numerical calculation.
