intake swirl 中文意思是什麼
intake swirl
解釋
進氣渦流-
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。 -
Analysis of external aerodynamic field characteristics under cold condition for dual - passage swirl oil burner with intake swirler
雙通道旋流式燃燒器出口冷態流場的流動特性分析 -
The distributing of the velocity in the intake port and on the port exit and the distributing of the turbulence kinetic energy are get. the momentum moment flow rate is used to scale the swirl. some advices to improve on the port are put forward
使用ansys的后處理模塊對計算結果進行處理，得到了氣道內、氣道出口的速度分佈、紊流動能分佈等結果，採用動量矩流率對渦流水平進行了評定，並對氣道的改進提出了一定的建議。
