CONDENSATION HEAT TRANSFER OF R-134A FLOW INSIDE HELICAL PIPES AT DIFFERENT ORIENTATIONS
Int. Coom. Heat Mass Transfer, Vol.30, No.6, pp. 745-754, 2003，-0001，（）：
This paper presents an experimental investigation of condensation heat transfer of alternative refrigerant R-134a flowing inside a helical pipe with cooling water through the concentric annular passage in a counter-flow direction. The experiments were conducted with the helix axis of the test section in horizontal, vertical, and inclined orientation directions, respectively. The mass flow flux for R-134a ranges from 100 to 400kg/m2s and the Reynolds number of cooling water ranges from 1500 to 10000. The results demonstrate the orientation of helical pipe has a significant effect on both refrigerant-side heat transfer and overall heat transfer coefficients.
