The effects of blowing and suction on forced convection and those on free convection over a extensively. On the other hand, the problem of free convection above a horizontal plate with blowing or suction has received substantially less attention. Gill et al. presented a local similarity solution for an isothermal horizontal plate with finite transverse velocity. Clarke and Riley, allowing for variable density, obtained a similarity solution for the special case of a plate with constant temperature and a particular distribution of blowing rate. The data available are quite restrictive. There is still a shortage of accurate data for a wide range of both suction and blowing rate. In this analysis of free convection over a semi-infinite horizontal plate, both the wall temperature and transpiration rate are assumed to be power-law variations. Finite-difference solutions and local similarity and nonsimilarity solutions are obtained over a wide range of transpiration rate from very strong suction to very strong blowing. Special considerations are given to the most practical cases of an isothermal plate under the condition of uniform blowing or suction.
