The heat transfer coefficient (CH) is a measure of how effectively heat is transferred between a solid surface and a fluid (liquid or gas) flowing over or around it. It is a critical parameter in heat transfer analysis and plays a crucial role in various engineering applications, such as designing heat exchangers, cooling systems, and thermal management solutions.
- CH: Coefficient of heat transfer (dimensionless).
- q̇w: Heat transfer rate (in W/m^2).
- ρe: Local density at edge of boundary layer (in kg/m³).
- ue: Local velocity at the edge of boundary layer (in m/s).
- haw: Adiabatic wall enthalpy (in J/kg).
- hw: Specific enthalpy of gas at the wall(in J/kg).
