| Abstract: | The cleaning principle of washing smoke system is analyzed, the concept of the system is designed, and a two-phase model of liquid and gas is set up. The size and position of the system is amended through numerical simulation of the interior flow field and temperature field of cascade style smoke eliminating system, and cascade structure is further improved by geometric model experiment. A washing smoke system sample is built and tested. The result shows that cascade style smoke eliminating system can well control the smoke, NO, and noise and has a good foreground in diesel engine after-treatment field. |
