Abstract
A distribution of instantaneous heat transfer coefficients around the flow reattachment region behind a two-dimensional backward-facing step was accumlated as time-continuous data, in order to clarify the heat transfer mechanism at that region. For this purpose, 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 on the condition that the maximum instantaneous heat transfer coefficient appeared at a specified heat flux meter. The position, where the peak in the ensemble-averaged distributions shows the maximum, located a about a one step height upstream of the time-averaged reattachment point. In general, the position of the maximum instantaneous heat transfer coefficient moves downward and appears discontinuously near the time-averaged reattachment point.
