摘要
The effect of heat-transfer strips on transition in flow over a flat plate is investigated. The maximum value of the integrated growth rate (N factor) of the instability wave is used as a measure of single-frequency (controlled, forced) transition, and the most upstream location at which N reaches a value of 9 is used as the location of the onset of wideband (natural) transition. The effects of the heat-transfer-strip location, the heating level, the length of the heat-transfer strip, the flow free-stream Mach number, and an isolated roughness element on single-frequency and wideband transition locations in subsonic two-dimensional flow are evaluated. The effect of heating strips on transition in three-dimensional and supersonic flows is discussed. (C) 1995 American Institute of Physics.
