| Abstract: | A method was presented to define the thermal boundary conditions of the nozzle in diesel engine.The thermal boundary conditions of the nozzle in a certain diesel engine were set up using the above method.3D finite element analysis of the thermal load of the nozzle was performed by using the ANSYS software.The temperature field,the thermal deformation and the heat stress field of the nozzle were obtained.These results are very useful for further failure analysis of nozzle and optimum design of its structure parameters. |
