【Abstract】 The prediction of heat transfer coefficients for nonazeotropic refrigerant mixtures during annular flow evaporation inside horizon taltubes is studied, and formulas for heat transfer coefficients is derived. The major factors on the evaporative heat transfer of nonazeotropic mixtures are analyzed. Calculated values are compared with the experiment data, and results show that they coincide with each other.更多还原
