The effect of exit back pressure and length / height ratio of isolator on forebody / inlet flow field is analyzed and discussed in the paper 本文還研究了隔離段出口反壓及隔離段長高比對進氣道流場的影響。
The results show the exit back pressure and length / height ratio of isolator have great impact on exit flow field and starting performance of inlet . high back pressure of inlet will result in unstart 研究表明:隔離段長高比對進氣道出口參數(shù)影響較大;隔離段出口反壓不能太高,否則會引起進氣道不起動。
However , for vertical roof solar chimney or inclined roof solar chimney with both ends open , either a large optimum gap - to - height ratio or no optimum chimney gap was found in the range of chimney gaps investigated 但是,對于帶有豎直集熱板或傾斜集熱板屋頂式太陽能煙囪(其特點是兩端完全開口) ,在研究范圍內(nèi),或者得到很大最佳的寬度與高度的比值,或者沒有找到最佳空氣通道寬度值。
