【 摘 要 】

The steady two-dimensional MHD mixed convection flow and heat transfer characteristics of an Oldroyd-B fluid over a linear stretchy sheet is considered. The flow caused by a linear stretchy sheet with effects of velocity, temperature and concentration slips. The thermal radiation, internal heat generation effects are included in the study. The resulting governing PDEs rebuild into ODE model by applying a suitable similarity transformation and then are solved by homotopy analysis method. The effects of the various constants on the velocity, temperature and concentration fields are discussed. It is found that the velocity, temperature and concentration fields decrease when increasing the corresponding slip constants.
