The characteristics of laminar natural convection about a vertical plate with periodically changing surface temperature have been studied by the finite-difference method. The effects of the amplitude and period of the surface temperature oscillation on the instantaneous and time-average Nusselt numbers, temperature and velocity profiles are demonstrated by several examples. High amplitude and a large range of frequency of the oscillation were considered in these examples. The time-wise variation of the fluid temperature in the inner region adjacent to the surface produces back heat flow at high amplitude, high frequency, and at high local Grashof number.

Free Convection Boundary Layer

The effect of small cross flow and surface-temperature variation on laminar free-convection boundary-layer characteristics along a vertical plate is studied by means of a perturbation analysis. First-order deviations from the quasi-two-dimensional solution are derived. The associated universal functions are calculated for two Prandtl numbers of 0.72 and 1.0. Essential results are given in both graphical and tabulated forms.
