Finally, the inlet port and combustion chamber designed and machined is tested on 4100qb. the paper mostly investigates the change of performance targets of the engine that three different grooved chambers including two different re - entrant model and one w model match with various intake port and nozzles, in order to realize the influence of chamber geometry on combustion process. the results analyzed have indicated that re - entrant grooved chambers can enhance the turbulent intension in the chamber, improve the combustion proces of diesel engine on the altiplano, being groove, re - entrant and convex, and have the farther developing potential
著重研究兩種縮口、一種直口矩形環槽燃燒室與不同進氣道、噴油嘴的組合方案發動機的動力性、經濟性及排放指標的變化，確定燃燒室的幾何形狀對燃燒過程的影響。分析結果表明，由於有矩形環槽、燃燒室縮口以及燃燒室底部凸臺，縮口矩形環槽燃燒室中的紊流得以加強，改善了高原柴油機的燃燒過程，這種燃燒室有進一步發展的潛力。In arbitrary curvilinear coordinates, the wall function is used for treating near wall regions. the influences of two different inlet gas parameter distributions and turbulent combustion models, as well as three different afterburners on turbulent combustion flow fields and wall temperature profiles are calculated. comparisons of experiment results and calculations results show that second - moment combustion model is reasonable for modeling turbulent reacting flows, inlet gas parameter distributions is more important. calculation method is reliable and can be used for the optimum design of afterburner
數值研究三種不同幾何形狀、兩種進口氣流參數分佈、兩種紊流燃燒模型等對加力室內各氣流參數、隔熱屏和加力室筒體壁面溫度分佈的影響，計算結果與試驗數據比較表明:不同幾何形狀加力室對加力室內紊流燃燒流場的影響要比進口氣流參數分佈大些，正確給定進口氣流參數分佈較為重要，二階矩紊流燃燒模型更適用摸擬三維紊流燃燒流動，計算方法合理，編制的計算程序可靠，可供加力燃燒室優化設計用。The numerical simulation of the inlet flow fields in the gas turbine. obtained numerical simulation results of flow fields include the uniformity, with the geometrical boundary completely according with the actual one and nothing being simplified
在幾何邊界形狀上嚴格反映物理真實而不作任何簡化，獲得了整個進氣系統地流場分佈狀況和壓氣機進口截面的不均勻度。
