| Abstract: | CFD simulation is carried out with the help of ANSYS CFX software on the coolant flow in the cylinder block and head of a high power intensity heavy-duty 6V engine to analyze the coolant flow distributions in every cylinder of the block and head as well as the coolant flow fields. Moreover, the influences of mesh number and mesh quality on the simulation accuracy are analyzed. The results shows that mesh number and mesh quality have much impact on the simulation accuracy. |
