Flow and heat transfer at a stagnation-point over an exponentially shrinking vertical sheet with suction

This paper investigate theoretically the problem of steady laminar two-dimensional boundary layer flow and heat transfer of an in compressible viscous fluid at a stagnation point over an exponentially shrinking vertical sheet with suction. In this study, we assume that the shrinking velocity and wal...
