A numerical method, previously used to calculate the momentum characteristics of laminar flow over an impulsively started circular cylinder, is used to solve the corresponding unsteady two-dimensional boundary-layer form of the energy equation. In regions where the streamwise velocity reverses its direction, the solution of the energy equation is modified by a procedure that accounts for the downstream influence. With this modification calculations are readily obtained for short and long times. Calculations are presented here for the entire surface of a cylinder with uniform wall temperature and for times, corresponding to tu∞/L, up to unity.
