Study of 3-D Gas Flow in Intake Duct of Internal Combustion Engine |
| |
| Abstract: | It is an important research program for studying gas flow in internal combustion engine by numerical simulation to find a reasonable way of arranging gas flow efficiently.The full three dimensional flow in the intake duct of internal combustion engine is calculated by means of ALE method.The results represent the influences of construction,geometric configuration,and size of the intake duct on the velocity and pressure distribution in the flow.The full three dimensional flow calculation can provide the reference for the construction and improvement. |
