Description

This paper provides new selection charts for the sizing ofadiabatic capillary tubes operating with alternative refrigerants.The mathematical model is based on conservation ofmass, energy, and momentum of fluids in the capillary tube.After the developed model is validated by comparison with theexperimental data reported in literature, selection charts thatcontain the relevant parameters are proposed for sizing adiabaticcapillary tubes. The selection charts are presented forsome alternative refrigerants and a wide range of operations.These newly developed selection charts can be practically usedto select capillary tube size from the flow rate and flow conditionor to determine mass flow rate directly from a given capillarytube size and flow condition.
