Greater heat generation

WebMar 17, 2024 · Many researchers have shown that adding surface enhancers such as ribs, cavities, fins, and dimples can improve heat dissipation, but this improvement comes at the cost of pressure losses since these structures induce secondary flow, vortices, and other disturbances. Several studies have focused on reducing these pressure losses. WebChapter 3: Heat Conduction Advanced Heat and Mass Transfer by Amir Faghri, Yuwen Zhang, and John R. Howell 3.3 Unsteady State Heat Conduction 7 For the case that the Biot number is greater than 0.1, the temperature distribution can no longer be treated as uniform and the knowledge about the temperature distribution is also of interest.
