Webconvection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to … WebMay 1, 2024 · The natural convection heat transfer rates from a horizontal cylinder can be enhanced 6 times by electrostatic cooling. Owsenek et al. found that at high voltages, negative ions produce less of a drop in the impingement point local heat transfer coefficient. This implies that a negative polarity corona wind generates less Joule heating than a ...
