Abstract
The thin film flow over a porous stretching sheet has been studied in presence of suction/injection under the assumption of uniform initial film thickness. It is also considered that the sheet is either heating or cooling along the direction of stretching. The rate of film thinning decreases with increasing the thermocapillary parameter when the sheet is heated and the opposite phenomena is observed for the sheet is cooled. The film thickness decreases with the increasing values of porosity parameter and suction velocity whereas it decreases with the increasing injection velocity. The temperature at a fixed height of the film decreases with the increasing values of porosity parameter and injection velocity, but it increases with increasing suction velocity when the sheet is heating. The opposite behaviour is observed when the sheet is cooling.
