Many of the difficulties just described are avoided by the use of an auxiliary ejector and an engine exhaust diffuser which are placed in tandem.
利用直列放置的發動機排氣擴壓器和輔助引射器,可以避免上述許多困難。The condensation heat - exchange characteristic of a separate - type heat - pipe was studied on a 1 : 1 model. the heat pipe is heated by electricity, and working fluid is distilled water, and it is cooled by air. the experimental results show that, ( 1 ) when charging liquid ratio is 45 %, condensation heat - exchange coefficient reaches to maxium ; ( 2 ) when there is not non - condensing gas, the coeffcient decreases a little with the increase of vapour pressure, and it decreases by 9. 5 % when the pressure increases from 0. 16mpa to 0. 36mpa ; ( 3 ) when there is non - condensing gas, the coefficient decreases a little, but when the gas is discharged by an exhaust value, it can be improved, when the volume content of the gas is 2. 5 %, it can increased by 22 % ; ( 4 ) the effect of the non - condensing gas on the coefficient decreases with the increase of the pressure, and when the volume content of the gas is 5 % and the pressure increases from 0. 16mpa to 0. 36mpa, the coefficient increases by 6 %. the relative curves are given between condensation heat - exchange coefficient and air flowrate, charging liquid ratio and vapour pressure
建立了空氣冷卻實驗臺,熱管的加熱方式為電加熱,工質為蒸餾水.在1 1模型上對分離式熱管管內凝結換熱特性、不凝性氣體對凝結換熱的影響及不凝性氣體的擴散規律進行了試驗,得出分離式熱管有一最佳充液率,其值為45 %左右;凝結換熱系數隨著蒸汽壓力的增加略有降低,在實驗的壓力范圍內,降低了9 . 5 % ;不凝性氣體對分離式熱管的凝結換熱僅影響冷凝段下部較小部分,通過排氣閥排出不凝性氣體可有效地改善冷凝段下部的凝結換熱;隨著壓力的增加,不凝性氣體對分離式熱管冷凝段的影響減少.這些結論可用於分離式熱管換熱器的工程設計和控制Abstract : the condensation heat - exchange characteristic of a separate - type heat - pipe was studied on a 1 : 1 model. the heat pipe is heated by electricity, and working fluid is distilled water, and it is cooled by air. the experimental results show that, ( 1 ) when charging liquid ratio is 45 %, condensation heat - exchange coefficient reaches to maxium ; ( 2 ) when there is not non - condensing gas, the coeffcient decreases a little with the increase of vapour pressure, and it decreases by 9. 5 % when the pressure increases from 0. 16mpa to 0. 36mpa ; ( 3 ) when there is non - condensing gas, the coefficient decreases a little, but when the gas is discharged by an exhaust value, it can be improved, when the volume content of the gas is 2. 5 %, it can increased by 22 % ; ( 4 ) the effect of the non - condensing gas on the coefficient decreases with the increase of the pressure, and when the volume content of the gas is 5 % and the pressure increases from 0. 16mpa to 0. 36mpa, the coefficient increases by 6 %. the relative curves are given between condensation heat - exchange coefficient and air flowrate, charging liquid ratio and vapour pressure
