Convection in heat exchanger
WebHeat flux is the rate of thermal energy flow per unit surface area of the heat transfer surface, e.g, in a heat exchanger. The main parameter while calculating heat transfer is heat flux. There are 3 types of generalized classification is there that helps to distinguish between heat fluxes by convection, heat conduction, and radiation. WebConduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles release electromagnetic … Why doesn't the heat transfer speed depend on the absolute temperatures … This means the heat flowing to your body per unit time, say 1 second. So if you …
