The present note treats a special case of a previous work published in Acta Mechanica (Kumari and Nath in Acta Mech 146:139-150, 2001). Analytical and asymptotic solutions are presented not found in the previous paper. [ABSTRACT FROM AUTHOR]

The flow of a non-Newtonian, power-law conducting fluid under the effect of a constant transverse magnetic field is considered. The flow is produced by a plate moving with constant velocity in a calm fluid. The plate is porous and fluid can either be sucked or injected through it. The boundary layer equations are transformed into a nondimensional form and are solved with a finite difference method. Part of this problem has been investigated in the past but only for suction and pseudo-plastic fluids. However, all flows of the present work reach an asymptotic state and exact analytical solutions exist for Newtonian fluids. In the present work we extend the investigation to both pseudo-plastic Newtonian and dilatant fluids in both suction and injection cases. [ABSTRACT FROM AUTHOR]

In a previous paper (Pantokratoras and Magyari, 2009), the Electro-Magnetohydro dynamic (EMHD) free convection flow of a weakly conducting fluid from an electromagnetic actuator was considered. In the present note, we study the cases where the Riga-plate either moves with constant velocity (Sakiadis flow) or the Riga-plate is situated in a constant free stream (Blasius flow). The results are obtained with the numerical simulation of the governing equations. Velocity profiles are presented, as well as values of the skin friction. Results are presented for both impermeable and permeable Riga-plate with uniform suction or uniform injection. [ABSTRACT FROM AUTHOR]

The Blasius and Sakiadis flows of a non-Newtonian power-law conducting fluid under the effect of a constant transverse magnetic field is considered. The boundary layer equations are transformed into a non-dimensional form and a new dimensionless magnetic parameter is introduced. The transformed boundary layer equations are solved with a finite difference method. Both Blasius and Sakiadis flows reach an asymptotic state and become one-dimensional with the increase of the coordinate in the streamwise direction. The flow behavior in the intermediate region is studied and exact analytical solutions have been found for the asymptotic state. The characteristics of physical and engineering interest are discussed in the paper in detail. [ABSTRACT FROM AUTHOR]

Abstract: The flow of a laminar wall plume in a constant transverse magnetic field is considered. The results are obtained with the numerical solution of the governing equations and cover both small and large ξ values and Prandtl numbers from 0.01 to 100. The similar wall plume has been investigated in the past but the nonsimilar has not been treated until now and it is solved here for the first time. [Copyright &y& Elsevier]

A correction to the article about thermal radiation effects on magnetohydrodynamic flow past a semi-infinite vertical plate in the presence of mass diffusion by E.M. Abo-Eldahab in the 2007 issue is presented.

Two serious errors exist in the above paper. • The comment concerns a paper published in Physica E. • The authors treated a nonsimilar problem as similar. • Two x-dependent parameters have been used instead of one. [ABSTRACT FROM AUTHOR]

The author offers his views on a paper by researcher K. Das related to effect of thermal radiation on magnetohydrodynamic (MHD) slip flow. Topics discussed include definition of electrical conductivity, dimensional nature of the magnetic parameter, intersection of the boundary conditions by the velocity and temperature profiles, ambient velocity and temperature, and the need for a larger calculation domain.

A theoretical study of the effect of a constant transverse magnetic field on the boundary layer flow over a vertical isothermal plate is presented in this note. The results are obtained with the direct numerical solution of the governing equations with primitive variables. The results cover both small and large ξ values, Prandtl numbers from 0.01 to 10 are the first complete accurate results for the classical MHD free convection flow along a vertical isothermal plate.
