...Hye Rim Kim; Seung Jin Song This paper presents a new analytical model of surge dynamics in turbo heat pumps. Turbo heat pumps use refrigerants as the working fluid and consist of a centrifugal compressor, condenser, expansion valve, and evaporator. Compared with a gas turbine engine, the turbo...

...Charles Matz; Giovanni Cataldi; Wolfgang Kappis; Gerd Mundinger; Stefan Bischoff; Eivind Helland; Matthias Ripken The results of a compressor flow-analysis code calibration study for estimating the effects of water evaporation within the blade rows of industrial axial compressors are presented...

...Qun Zheng; Yufeng Sun; Shuying Li; Yunhui Wang Thermodynamic model of wet compression process is established in this paper. The topics of ideal wet compression process, actual wet compression process, water droplet evaporative rate, wet compression work, inlet evaporative cooling, concept of wet...

... size remains the same at all locations except for the region close to the heated surface, where the droplets become smaller along the wall because of evaporation. The heat flux on the heater can be obtained from the heating power divided by the heating area, assuming the heater has a uniform...
