Numerical Simulation of Flow Resistance and Acoustic Performance of High-power Diesel Exhaust Cooling Silencer
The fluid and heat transfer effect of exhaust cooling silencer are simulated by FLUENT software which bases on the finite volume method. Transmission loss of environment temperature without cooling water and high temperature with cooling water is calculated by SYSNOISE software which bases on the finite element method. The peak of the transmission loss curve will move to the as the temperature increasing. Some useful conclusions for design of the exhaust cooling silencers of high-power diesel engines are given.
silencer numerical simulation, cooling effect, temperature field, transmission loss silencer is calculated.
