例句與用法

The results indicate that : the high positioned air inflow do good to heat transfer in rotator disk ; different size of radial outflow have small effects on flow and heat transfer ; the heat transfer near rotating disk increases as rotating reynold number increases or non - dimensional mass flow rate increases
結(jié)果表明，高位軸向進(jìn)氣對(duì)轉(zhuǎn)盤換熱有利；不同的徑向出口大小對(duì)盤腔內(nèi)的流動(dòng)換熱影響不大；隨旋轉(zhuǎn)雷諾數(shù)和無(wú)量綱質(zhì)量流量增加，轉(zhuǎn)盤盤面的換熱效果增強(qiáng)。
By comparing the results with relative experiment data , it is shown that rng k - is more exactly than the other turbulent model . . 2 ) the influences of axial inflow position , radial outflow size , rotating reynold number , non - dimensional mass flowrate and axial inflow angle on the flow and heat transfer characteristics were numerically investigated for a typical rotator - stator cavity with axial inflow , radial inflow and radial outflow . the correlations for average nusselt number vs rotating reynold number or non - dimensional mass flowrate were established
( 2 )針對(duì)一典型的徑向、軸向進(jìn)氣，徑向出氣的轉(zhuǎn)-靜盤腔結(jié)構(gòu)，系統(tǒng)研究軸向進(jìn)氣位置、徑向出口大小、旋轉(zhuǎn)雷諾數(shù)、無(wú)量綱質(zhì)量流量和軸向垂直預(yù)旋進(jìn)氣等對(duì)盤腔內(nèi)流動(dòng)和換熱的影響，整理出轉(zhuǎn)-靜盤腔內(nèi)轉(zhuǎn)盤平均努謝爾數(shù)與旋轉(zhuǎn)雷諾數(shù)無(wú)量綱質(zhì)量流量之間的準(zhǔn)則關(guān)聯(lián)式。
3 ) a custom filed function module was complied to study the influence of non - dimensional mass flowrate changed with time in stair shape on flow and heat transfer inside rotator - stator cavity with axial inflow and radial outflow . average nusselt number takes on a sharp up - down process when the mass flowrate changes from stabile status as to the following change of flowrate , the average nuselt number changes greatly in the initial stage and then changes gradually
( 3 )自編用戶程序模塊，研究在軸向入流、徑向出流的轉(zhuǎn)-靜盤腔中，無(wú)量綱流量隨時(shí)間呈階梯型改變對(duì)盤腔流動(dòng)和換熱的影響。當(dāng)流量從某個(gè)穩(wěn)定狀態(tài)改變時(shí)，轉(zhuǎn)盤上的平均努謝爾數(shù)會(huì)產(chǎn)生一個(gè)明顯的上升再降低過(guò)程；在每一次流量改變的初始階段，平均努謝爾數(shù)存在一個(gè)較大幅度的變化。
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(jié)果表明，預(yù)旋進(jìn)氣的優(yōu)點(diǎn)在于增強(qiáng)了葉片冷卻孔附近的對(duì)流換熱效果，局部努謝爾數(shù)隨預(yù)旋角的增大而有所減小；隨旋轉(zhuǎn)雷諾數(shù)的增加，不論是內(nèi)轉(zhuǎn)靜腔室還是預(yù)旋腔室的靜盤上的溫度都不同程度的降低：當(dāng)軸向中心進(jìn)氣質(zhì)量流量不變時(shí)，隨預(yù)旋進(jìn)氣的質(zhì)量流量增加，內(nèi)轉(zhuǎn)靜腔室的轉(zhuǎn)盤盤面上的換熱基本沒(méi)有變化，而預(yù)旋腔室的轉(zhuǎn)盤盤面上的換熱效果增強(qiáng)；當(dāng)預(yù)旋進(jìn)氣質(zhì)量流量不變時(shí)，軸向中心進(jìn)氣的質(zhì)量流量的改變對(duì)整個(gè)盤腔都有影響。
