flowing in a plate heat exchanger were investigated experimentally in this study. Two vertical …

Pressure drop experiments were performed in small channels with three refrigerants: R-
134a, R-12, and R-113. The channel size simulates flow passages in compact evaporators …

In this study, the two-phase heat transfer coefficient characteristics of HFC-134a evaporating
under forced flow conditions inside a smooth horizontal tube are experimentally …

An average R12 refrigerant correlation has been developed for the mass flux range of 25-
100 kg/m2-s and the heat flux range of 2-10 kW/m2. Refrigerant mixtures of 80% R22/lO …

Flow boiling heat transfer characteristics of R134a were experimentally investigated in a
horizontal stainless steel mini-tube. The inner diameter of the test tube is 1.3 mm and the …
