4 ) in a pre - swirl rotator - stator cavities with discrete pre - swirl nozzles and blade - cooling entry holes, the influences of pre - swirl angle and flow parameter on the flow and heat transfer characteristics were numerically investigated. the correlation for average nusselt number vs rotating reynold number or non - dimensional mass flowrate were established. the results show that : advantage of per - swirl inflow is the effect of cooling the blade - cooling entry holes ; pre - swirl inflow increases heat transfer in rotating disk of pre - swirl chamber ; as pre - swirl angle increases, local nusselt number decreases in pre - swirl chamber ; the temperature of stator of inner rotator - stator chamber and per - swirl chamber decreases as rotating reynold number increases ; when the axial mass flowrate maintains constant, heat transfer in the rotating disk of inner rotator - stator cavities does n ' t change as per - swirl mass flowrate increases, while heat transfer in the rotating disk of per - swirl chamber increases ; when the pre - swirl mass flowrate maintains constant, change of the axial mass flowrate has effect on the whole cavity
結果表明，預旋進氣的優點在於增強了葉片冷卻孔附近的對流換熱效果，局部努謝爾數隨預旋角的增大而有所減小；隨旋轉雷諾數的增加，不論是內轉靜腔室還是預旋腔室的靜盤上的溫度都不同程度的降低：當軸向中心進氣質量流量不變時，隨預旋進氣的質量流量增加，內轉靜腔室的轉盤盤面上的換熱基本沒有變化，而預旋腔室的轉盤盤面上的換熱效果增強；當預旋進氣質量流量不變時，軸向中心進氣的質量流量的改變對整個盤腔都有影響。 -
Results show that all the geometric parameters have remarkable effects on combustion performance ; the swirl of intake air generated by skew intake holes enhances fuel - air mixing, minimizes dead zone and stabilizes the flame with reverse flow, but the excessive reverse flow can cause overheat in combustion chamber and exhaust ; the consistency of flow resistance in intake and exhaust system is conducive to the stability of heater performance
研究表明，燃燒室進氣孔的孔徑、孔數、孔的分佈及方向等均對燃燒性能影響很大；斜孔所產生的旋轉進氣，雖具有強化燃氣混合、消除死區和迴流穩焰的作用，但迴流過度會使燃燒室及排溫過高；保證進排氣系統流動阻力（壓力）的一致性，有助於保證加熱器性能穩定。 -
