Abstract:

The report presents a survey and evaluation of the numerous techniques which have been shown to augment convective heat transfer. These techniques are surface promoters, including roughness and treatment displaced promoters, such as flow disturbers located away from the heat-transfer surface vortex flows, including twisted-tape swirl generators vibration of the heated surface or the fluid near the surface electrostatic fields and various types of fluid additives. Natural and forced convection situations for nonboiling, boiling, and condensation heat transfer are included. The conditions under which heat transfer is improved are summarized, and the efficiency of each technique is presented in terms of a performance criterion where possible. Author
