that the variation trends of mass flow rate of all working fluids are the same. A rise in evaporating temperature decreases the mass flow rate. Based on the law of energy conservation, the mass flow... temperature versus the evaporating temperature for various working fluids is presented in Fig. 7. As shown, the rise of Tsv,out is proportional with Te, and the change rate of Tsv,out to Te is almost......

The friction and temperature rise on the marine gear tooth surfaces depend mainly on the meshing conditions in the asperity-contact regions. The contact pressure between two meshing teeth is often greater... distributed roughness on the surfaces will inevitably affect the mixed lubrication behavior, friction coefficient and temperature rise. Figure 5(b) presents the variations of friction coefficient μ......
