Enthalpy is a thermodynamic property that represents the total heat content of a system at a constant pressure. It combines the internal energy of a system with the product of its pressure and volume. An adiabatic wall refers to a hypothetical boundary or surface in a thermodynamic system that is assumed to be perfectly insulated or impermeable to heat transfer. In other words, it does not allow any heat exchange with its surroundings. As a result, the temperature on either side of an adiabatic wall can change due to internal processes or changes in the system, but there is no heat flow across the wall itself.Â
- haw is the adiabatic wall enthalpy
- he is the enthalpy at the edge of the fluid boundary
- r is the recovery factor
- ue is the velocity of the fluid at the edge
