| Abstract: | Based on the heat transfer mechanism and hydrodynamics,a numerical method is used to simulate the proximal geometrical dimension of capillary tube and the change of dimensions along with the change of working conditions.Corresponding physical and mathematical models are constructed.A computer program is developed,which uses the numerical method to solve the mathematical model and succeeds in calculating the capillary tube length in propane refrigerating system.The study provides good references for the selection of capillary tubes. |
