| Inhoud: |
Time-serial data were accumulated for the distribution of instantaneous heat transfer coefficients around the flow reattachment region behind a two-dimensional backward-facing step, in order to clarify the heat transfer mechanism at that region. Ten heat flux meters, based on a constant-temperature method, were arrayed on the bottom surface of the step. The ensemble-averaged heat transfer coefficients were calculated under the condition that the maximum heat transfer coefficient appeared at a specified heat flux meter. On the average the peak value of the instantaneous heat transfer distribution shows a maximum at about one step height upstream position from the time-averaged reattachment point. In general, the position of the maximum instantaneous heat transfer coefficient moves downward and appears discontinuous^ near the time-averaged reattachment point. |
