Proc. ASME. HT2020, ASME 2020 Heat Transfer Summer Conference, V001T12A005, July 13–15, 2020
Paper No: HT2020-8938
... Abstract Steam condensation heat transfer was studied over a honeycomb-like microporous superhydrophobic surface under various pressures, in order to elucidate the effects of pressure on the jumping-droplet condensation behaviors. The condensing pressure was varied from 4 kPa to 13 kPa, based...

Proc. ASME. HT2003, Heat Transfer: Volume 2, 429-434, July 21–23, 2003
Paper No: HT2003-47236
... This paper presents an experimental investigation of condensation heat transfer and pressure drop characteristics of refrigerant R-134a flowing through an annular helicoidal passage with the hydraulic diameter of 8.5 mm. The angles of helix axis are oriented at 0, 45, 90 degrees to gravity...
