【Abstract】 The blocked coupling technique by Poisson Equation as controlling is applied for generating three dimension body fitting grid in the inlet channel of diesel engine. Euler Equation is solved by means of the finite control volume method. Full three dimension flow fluid is calculated in the inlet channel of diesel engine. The calculation result represents that the construction, geometric configuration, and size of the inlet channel influences on the velocity and pressure distribution in its flow fluid. The full three dimension flow computation can provide the theoretical grounds for the construction and improvement.更多还原
