Web27 apr. 2024 · Introduction. The heat transfer coefficient describes the convective heat transfer from a solid to a flowing fluid (gas or liquid) or vice versa. Such a situation can be seen, for example, with a radiator. Cold air flows past the radiator due free convection and is heated. Obviously, the radiator transfers heat to the passing air. WebLatent heat does not impact the temperature of something. The temperature of boiling liquid water and the resulting gas (water vapor) are both 100° C, even though energy is put into the water to convert it from liquid to gas. What is heat transfer? If heat is a form of energy, then “heat transfer” is the transfer of energy.
