Web2 Feb 2024 · The convective heat transfer coefficient is the rate of heat transfer between a solid surface and a fluid medium per unit surface area per unit temperature difference. From the definition, we can easily infer that this heat transfer coefficient depends on the properties of both the solid object and the surrounding fluid medium . WebThe convection coefficient outside and inside is determined to calculate the heat flux of the roof with different insulation thickness. The heat flux gained by the roof reaches the highest value at 1 pm which is 0.648 W/m² without insulation. The heat flux has been reduced to 0.629 W/m² after applying one layer of glass wool insulation.
