Heat is the transfer of thermal energy
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (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 (mass transfer in the form of advection), either cold or hot, to achieve heat tra… Web12 de abr. de 2024 · After comparing the various working fluids which are used in parabolic trough collectors (PTC), it is found that Liquid Sodium is the most reliable heat transfer …
