The homogeneous flow approach is suitable for refrigerant two-phase flow modeling. The superposition principle is appropriate where suitable correlations are missing. Transient models of refrigeration systems require correct OFF-cycle modeling. Helically coiled double tubes with inner fluted tube experience high pressure drop.
