摘要
本文以计算传热学、流体力学为研究手段 ,利用数值计算的方法模拟出所需毛细管的最佳几何尺寸及随工况变化时的情况 ,建立相应的物理模型和模型、编制程序 ,计算出以丙烷 ( R2 90 )作工质的小型制冷设备毛细管的长度 ,为毛细管的选择建立一定的理论依据 .
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.
