ExHFT for fourth generation heat transfer technology

This review paper considers the many techniques that have been developed to enhance convective heat transfer. A summary is given of the techniques that are effective for the various modes of heat transfer. Of particular interest currently is compound enhancement that involves the simultaneous application of several techniques, so as to produce an enhancement that is larger than the individual techniques operating separately. This is considered fourth generation heat transfer technology. To realize this, there are many experimental challenges to be overcome that relate to obtaining and applying data.
