Heat transfer analysis for magnetohydrodynamics axisymmetric flow between stretching disks in the presence of viscous dissipation and Joule heating

Blog Article

The investigation of heat transfer analysis on steady here MHD axi-symmetric flow between two infinite stretching disks in the presence of viscous dissipation and Joule heating is basic objective of this paper.Attention has been focused to acquire the similarity solutions of the equations governing the flow and thermal fields.The transformed boundary value problem is solved analytically using homotopy analysis method.The series solutions are developed and the convergence of these solutions is explicitly discussed.

The analytical expressions for fluid velocity, pressure and temperature are constructed and analyzed for various set of parameter values.The numerical values for skin friction coefficient and the Nusselt number are presented in tabular form.Particular attention is given to the variations of Prandtl and Eckert numbers.We nightstick twm-850xl examined that the dimensionless temperature field is enhanced when we increase the values of Eckert number and Prandtl number.
