Abstract : A new solution is found from the M. H. D. pipe flow equations which exhibits the reverse flow phenomenon when the Hartmann number exceeds a certain critical value. The reverse flow region separates from the wall of the channel at a second higher Hartmann number, and the variation of the critical Hartmann number with changes in geometry of the boundary is discussed numerically. The induced magnetic field also demonstrates a similar phenomenon and changes its direction after the fluid velocity changes sign. The flow is also discussed in relation to its expansion in terms of the Hartmann number. (Author)
