| Abstract |
The present study has been experimentally investigated the effect of geometric and operating parameters on the two-phase flow distribution of refrigerants in a horizontal T- junction. The operating parameters were the kind of refrigerants(R-22, R-134a, and R-410A), saturated temperature, and the inlet mass flux and quality. The geometric parameters were the tube diameter and the tube diameter ratio. The measured data of refrigerants were com-pared with the values predicted using the models developed by several researchers for air/ water or steam/water two-phase flow. Among the operating parameters, the inlet quality was the most sensitive to the mass flow rate ratio. Between the geometric parameters, the tube diameter ratio was more sensitive than tube diameter. |
