Heat and mass transfer from a horizontal slender cylinder with a magnetic field effect

The problem of steady laminar magnetohydrodynamic (mhd) forced convective heat and mass transfer about a horizontal slender cylinder is studied numerically. a uniform magnetic field is applied perpendicular to the cylinder. the nonlinear partial differential equations governing the flow are transformed into the similar boundary layer equations,which are then solved numerically using the keller box method. the transverse curvature parameter,the magnetic parameter,the prandtl number and the schmidt number are the main parameters. for various values of these parameters,the local skin friction,heat transfer and mass transfer parameters are obtained. the validity of the methodology is checked by comparing the results with those available in the open literature and a fairly good agreement is observed. finally,it is determined that the local skin friction coefficient,the local heat transfer coefficient and the local mass transfer coefficient increase with an increase the magnetic parameter mn and transverse curvature parameter. ©2008 tibtd printed in turkey.
