Heat transfer coefficient calculator

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).
