The performance of energy separation on the vortex tube designed by the author is studied at different cold mass flow ratios , and the characteristic curve has been drawn 對于本文設計的渦流管,研究了不同冷氣流率時渦流管的能量分離特性,并且繪制了性能曲線。
The experimental results show that adiabatic efficiency has a remarkable improvement in low cold mass flow ratios , adiabatic efficiency can improve by 30 % in the best condition 實驗表明,在冷流率小的情況下,通過加濕可以使得絕熱效率得到顯著的提高,最好可以提高30 。
For example , existing flow ratios can ' t provide the composition of current asset , and the users of financial statements can ' t understand the specific weight of each element of current asset clearly 比如,現行的流動比率不能提供流動資產的構成,報表使用者不能清晰地了解流動資產各要素的具體權重。
When there is no impingement , the investigation about flow extravasation effect form film cooling holes is carried out with different cross flow reynolds numbers and different density flow ratios of the film outflow to cross flow 在無沖擊射流時,通過改變來流雷諾數、氣膜出流與橫流密流比,對氣膜孔的“溢流效應”進行了研究。
The experiments indicate that the deposition rate will increase with the increase of the flow ratio of sihu / nhs , slightly decrease with the increase of substrate temperate , and increase obviously with the increase of rf power 氮化硅薄膜的折射率隨硅烷氨氣流量比增大而增大,隨溫度升高而略有增加,隨淀積功率增大而略為降低。
At the same time the number of holes for liquid flowing , gas flowing and blocked to the number of total holes was defined as liquid flowing ratio , gas flowing ratio and blocked ratio . the experiment was made with in - diameter 500mm column using water - air system , the ratio was first delected in detail by multi - path conductivity gauge for the compound tray with free area 20 % and 25 % respectively 采用多路電導測試儀,在直徑500mm的冷模塔內,以空氣-水為介質,首次較系統地測量了開孔率為20和25的復合塔板的通氣、通液和阻塞篩孔的數量比例,獲得了通氣率、通液率和阻塞率隨氣液變化的基本規律。
( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value , the flow of atomizing of gas and the range of the inverse vortex taper . the more of the value of three factors , the more advantage they are for the atomization and the more fine the powders are . ( 4 ) the produced powders are the best in efficient atomization efficiency , particle diameter , particle shape and dispersion when the solder alloy is zhl63a , atomizing medium is n2 , the protrusion h = 6 . 0mm , atomizing gas pressure p = 100mpa , over - heat temperature t = 167 ( t = 350 ) 研究結果表明: ( 1 )超音速霧化器的氣體流場在導液管下端形成一個倒渦流錐,在二維空間上呈軸對稱的雙峰分布,負壓形成于這個倒渦流錐內; ( 2 )修正后的霧化氣體速度公式可以滿足超音速霧化的要求; ( 3 )影響超音速霧化工藝最根本的因素有氣液質量流率比( gmr )的大小、霧化氣體流量和倒渦流錐范圍,三個因素的值越大,對形成細粉越有利; ( 4 )在焊錫合金為zhl63a ,霧化介質微n _ 2 ,導液管突出高度取h = 6 . 0mm ,霧化氣體壓力取p = 1 . 0mpa ,合金過熱度取t = 167 ( t = 350 )時,所制得的粉末在有效霧化率、顆粒球形度、粒度及其離散度三個方面綜合性能最好。
