摘要: Abstract An analysis is made for the unsteady two-dimensional magneto-hydrodynamic flow of an incompressible viscous and electrically conducting fluid over a stretching surface having variable general form temperature which removes restrictions particular forms prescribed temperature. Similarity solutions transformed governing equations are obtained. The boundary layer solved numerically some values involved parameters, namely unsteadiness parameter, magnetic exponent parameters. features heat transfer characteristics different parameters analysed discussed. It found that velocity decrease increasing parameter. Fluid decreases with Hartman number resulting increase in field steady as well case. observed variation sheet respect distance time has analogous effects both on free rate (Nusselt number) at sheet.
