Abstract
A new method for convective heat transfer enhancement is described. Th e technique involves the use of a pulse combustor to generate a transi ent jet that impinges on a flat plate. Enhancements in convective heat transfer of a factor of up to 2.5, compared to a steady impinging jet at approximately the same Reynolds number, have been obtained. seat t ransfer data for several experimental configurations are presented. Fl ow field visualizations and theoretical calculations are used to sugge st an enhancement mechanism.
