✦ Synopsis

The response of laminar boundary layer flow past a semi-infinite flat plate to harmonic oscillations in the plate temperature in the form of a travelling wave convected in the direction of the free-stream has been studied here. Series solutions in terms of the small amplitude and the small oscillations to the non-linear system have been derived and the resulting nonlinear ordinary equations due to usual similarity transformations are solved numerically. The function affecting the temperature is shown on a graph. Due to greater viscous dissipative heat the function/(1, increases and it decreases with increasing Prandtl number. Also the time averaged heat flux function K~(0) increases with Prandtl number and decreases due to greater viscous dissipative heat.
