HYDROMAGNETIC CONVECTION FLOW THROUGH A POROUS MEDIUM IN AXIALLY VARYING PIPE
The hydromagnetic mixed convection flow through a porous medium in a pipe of varying radius in a uniform axial magnetic field is analyzed. The pipe wall is maintained at a prescribed nonuniform temperature. The governing equations are solved analytically to obtain the velocity, temperature, and induced magnetic field. Their behaviors are evaluated for different variations in the governing parameters. Department of Mathematics, S. K. University, Anantapur - 515003, (A.P.) India.
