| Abstract: | The difference in air flow in a swirl chamber from that in a swirl chamber with a variable passage and the effect of geometric parameters of the swirl chamber with a variable passageon the air flow are analyzed.From computation and test results obtained,the best range ofpassage geometric parameters of the swirl chamber with a variable passage are presented.The flow characteristics are helpful to the speed-up of the combustion of fuel-air mixture andto the reduction of the flow loss.Therefore,the thermal efficiency is higher than that of ageneral swirl chamber. |
