In order to investigate the characteristic of boiling heat transfer for mixture refrigerant in plate-fin heat exchanger, a model was established on boiling heat transfer in vertical rectangular minichannel. Based on the interfacial length scale derived by theory principle, the characteristic of boiling heat transfer was simulated for mixture refrigerant in vertical rectangular minichannel by Euler-Euler model in CFX. The simulation results were also compared with some correlations in literatures. The results show that the boiling heat transfer coefficient decreases with the increase of quality because of the influence of the material property for boiling heat transfer. At the same time, the boiling heat transfer coefficient increases as the mass flow rate and heat flux increase. This is because that the convection boiling and nucleate boiling is main heat transfer mechanism in a vertical rectangular minichannel. The Lazarek's correlation calculations agree well with the simulation results and the error between the simulation results and Lazarek's correlation is within ±15%. These results will provide some constructive instructions in the design of boiling heat transfer characteristics for plate-fin heat exchanger. ©, 2015, Beijing Institute of Technology.

To deeply understand the performance of high pressure common rail diesel engine, and so as to safely operate it, the general mathematical model for continuous time domain was established based on lookup tables and formulas, and the simulations were conducted. Modular mathematical modeling was established respectively for the high pressure pump, the intermediate oil reservoir and the common rail of the high pressure common rail system, and then, the whole system was formed. Simulations were done by using Matlab/Simulink. Simulation results compared with the experimental data show the correctness of the model.

The interfacial length scale which affect the simulation accuracy of boiling heat transfer was derived by theorety principle. The boiling heat transfer in vertical rectangular channel was simulated by CFX based on Euler-Euler model. The simulation was validated by the experiment data in literature. The result show that the error between simulation and experiment is within ± 15%. These results would provide some constructive instructions in interfacial length scale which is determined in CFX and the investigation of boiling heat transfer mechanism in vertical rectangular channel. © (2014) Trans Tech Publications, Switzerland.
