ProfessorMajid Ghassemi, Dr.Azadeh Shahidian, in Nano and Bio Heat Transfer and Fluid Flow, 2017. 3.1.1 Conduction Heat Transfer. Conduction heat transfer is the transfer of heat by means of molecular excitement within a material without bulk motion of the matter. Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion.
2019-12-31 · Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy 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
