| Abstract: | A physical model for numerical simulation and calculation of cross horizontal-tube falling film evaporator used in air-conditioning and refrigeration system was presented. For different configuration of the distributor, the flows of R134a outside the horizontal tube under different working conditions were simulated and calculated. The distribution of film thickness around the horizontal tube circle under different working conditions was obtained by the software TECPLOT. |

| Keywords: | horizontal-tube falling film evaporator numerical simulation flow regime falling film |
