Convection heat transfer applications
WebAs the name suggests, heat transfer is the travel of heat or thermal energy from one object or entity to another. This transfer takes place in three ways – conduction, convection, and radiation. This ScienceStruck post … WebNatural convection heat transfer in porous media has long been studied as it is a representative model problem for numerous engineering applications such as in electronics cooling, heat exchangers, and various thermal systems (see some works in Nield and Bejan, 1998 and Sohouli et al., 2008).
