Diffusion heat transfer is due to random molecular motion. Neighboring molecules move randomly and transfer energy between one another - however there is no bulk motion. Radiation heat transfer, on the other hand, is the transport of heat energy by electromagnetic waves. All bodies emit thermal radiation.
The Bend Heat Transfer model uses an empirically derived equation for the calculation of the heat transfer coefficient a in bends . The model is applicable for one and two phase flows. In the case of the fluid being in form of a liquid or gas, the thermal conductivity and hydraulic diameter are used to calculate the convective heat transfer coefficient using the formula:. In the case that the fluid is evaporating Shah and condensing Shah the relations for the calculation of the two-phase convective heat transfer coefficient are used. The heat transfer coefficient a Liq T is calculated as if only saturated liquid flows with the complete mass flow rate through the pipe.
