Fundamentals of Heat Transfer (What is it?)

Share This: Heat transfer is the flow of thermal energy driven by thermal non – equilibrium (i.e. the effect of a non – uniform temperature field), commonly measured as a heat flux (vector), i.e. the heat flow per unit time (and usually unit normal area) at a control surface. The aim here is to understand heat transfer modelling, but the ... Read More »

Why Heat and Mass Transfer?

Share This: Heat transfer and mass transfer are kinetic processes that may occur and be studied separately or jointly. Studying them apart is simpler, but both processes are modelled by similar mathematical equations in the case of diffusion and convection (there is no mass – transfer similarity to heat radiation), and it is thus more efficient to consider them jointly. ...
