CAPILLARY TUBE

This case study demonstrates the modeling of a capillary tube. Capillary tubes are used as expansion devices on some vapor-compression refrigeration systems. The refrigerant used in this case study is R22.

"Flownex® was used to determine the mass flow of R22 through a capillary tube given the inlet pressure and temperature and the outlet pressure. This case study demonstrates Flownex’s ability to calculate two-phase flow in a tube including choking at the exit."
