摘要:Simulation models of resistance mufflers with different typical structures were established, through the computational fluid dynamics method, under the conditions of different inlet velocities, by analyzing distribution characteristic of velocity field and pressure field for flows internal the mufflers, a kind of mathematical relation among the inlet velocity, inlet/outlet pressure, and pressure loss was discovered. Through CFD simulation computation and practical measuring tests of above three parameters for practical muffler with complex configurations, the mathematical relation of them was proved to be correct. With the conclusion, while inlet velocity changed, the variable conditions of inlet/outlet pressure and pressure loss for resistance mufflers could be estimated approximately Therefore, the test expense could be saved, and the designing efficiency for mufflers could also be further improved, so it would bring a certain economic benefit, which would be of great significance for energy saving research of mufflers.
