摘要:
The numerical simulation of wing-and-tube evaporator tube side in organic Rankine cycle(ORC)system is carried out based on CFD method, the accuracy of the simulation model is verified based on experimental data from the engine-ORC joint system test bench, and the flow and phase change heat transfer characteristics of the working fluid R245fa on the tube side are analyzed. By changing the engine speed, evaporation pressure and the inlet speed of the pipe side working fluid, the flow and heat transfer characteristics of the working fluid under different working conditions are compared and analyzed. The results show that the engine speed, evaporating pressure and the inlet speed of working fluid in the tube side have a great influence on the evaporation of working fluid. The engine speed has little effect on tube side inlet and outlet pressure drop. The evaporating pressure and the inlet speed of working fluid have the great influence on inlet and outlet pressure drop in the tube side. © 2018, Editorial Board of Acta Energiae Solaris Sinica.
