The influence of two dimensional unsteady disturbances on the velocity and the temperature distributions of time mean is considered theoretically for the laminar flow over a flat plate and the flow between two flat plates. On the plates sinks and sources are uniformly distributed and the blowing and the suction rates of these sinks and sources vary in time and space sinusoidally so that the sinks and sources seem to progress two dimensionally over the plates. The velocity amplitude of these blowing and suction rates is small compared with the uniform flow velocity. The fundamental equations for these flows are obtained and solved analytically. From these solutions it is shown that the velocity and the temperature distributions are very different from the distributions without the disturbances, even when the blowing and the suction rates are very small. It is also shown that the Reynolds analogy is approximately applicable to these flows.
