Htc Heat Transfer Coefficient. The rate of heat transfer between a solid surface and a fluid per unit surface area per unit temperature difference. The heat transfer coefficient htc is a very important factor influencing the energy performance of a building.
Htcqwalltwall tref for forced convection flows htc is traditionally conceived to be a function of velocity flow rate fluid properties and geometry. The convective heat transfer coefficient is dependent upon the physical properties of the fluid and the physical situation. Recent studies have shown the importance of on site measurements of the htc in reducing the performance gap in buildings.

The heat transfer coefficient is indicative of the effectiveness for the rate of heat transport through a domain between the surface and the fluid. The convective heat transfer coefficient is dependent upon the physical properties of the fluid and the physical situation. It is used in calculating the heat transfer typically by. The heat transfer coefficient has si units in watts per squared meter kelvin.
