Abstract

Abstract: The reliability of high pressure common rail injector depends on the calculation accuracy of its temperature changing. Due to the temperature measurement limitation and difficulty, in order to obtain more detailed temperature distribution, a coupling physical model is established in this paper based on multi-fields coupling analysis method, and a method based on the uni-directional coupling for calculating the temperature distribution of injector accurately is developed. The results show that the convective heat transfer coefficient varies with the flow state and the multi-field coupling method can correct the convective heat transfer coefficient according to the flow state automatically, which improves the prediction accuracy of the actual temperature distribution of the injector and provides a common solution frame for similar fluid-solid coupling problems.
