The convective heat transfer coefficient (h),defines,in part,the heat transfer due to convection.The convective heat transfer coefficient is sometimes referred to as a film coefficient and represents the thermal resistance of a relatively stagnant layer of fluid between a heat transfer surface and the fluid medium.Common units used to measure the convective heat transfer coefficient are Convective Heat Transfer Coefficient - Nuclear PowerTypically,the convective heat transfer coefficient for laminar flow is relatively low compared to the convective heat transfer coefficient for turbulent flow.This is due to turbulent flow having a thinner stagnant fluid film layer on the heat transfer surface..It must be noted,this stagnant fluid film layer plays crucial role for the convective heat transfer coefficient.

In the above equation h represents the convective heat transfer coefficient.To determine what this value is you will need to have an understanding of laminar and turbulent flow.Laminar flow occurs when there are distinct fluid layers through the boundary layer of the fluid.Convective Heat Transfer Coefficients Table Chart
