    Abstract

    An analysis is carried out to study the heat transfer characteristics in an electrically conducting fluid over a stretching sheet with variable wall temperature and internal heat generation or absorption. Two cases are studied, namely, (i) the sheet with prescribed surface temperature (PST case) and (ii) the sheet with prescribed wall heat flux (PHF case). The solutions for the temperature, the heat transfer characteristics and their asymptotic limits for large Prandtl number (sigma) are obtained in terms of Kummer's and parabolic cylinder functions. It is shown that asymptotic limits are not possible for small Prandtl number, this is due to the solution changing by O(1) on length scale of 1/sigma. For large Prandtl number, a boundary layer of width 1/sigma at eta = O and an internal layer of width square-root 1/sigma near the turning point are noticed.
