Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy and heat between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.
Scientists have described and proven how many of the world’s phenomenae function, from the very fundamental laws of Newtonian mechanics, to the discrete behaviors of quantum physics, eventually peering through some of the Universe’s most well kept secrets. It’s remarkable then, how little we know about how heat is conducted through and between materials. A better [...]
