Mark - to - space ratio
標(biāo)間比率
It is necessary to point out that the covered end thickness of back covered porous brick is increasing as the machine wearing , and it results in the decreasing pore space ratio
但是，由于盲孔多孔磚機(jī)沖頭不斷磨耗，如不及時(shí)更換，將使盲端厚度隨之增大，致使磚的孔洞率降低。
The thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed channel are measured by using infrared camera and then the impingement cooling heat transfer coefficients are deduced . the effects of flow and geometry parameters on convective heat coefficients are obtained . the results show that : for a single row normal impingement , the impingement cooling effectiveness is enhanced with the increase of impinging reynolds number or the decrease of hole space to diameter ratio , and the best effectiveness is achieved under the jet - to - surface spacing equals to 2 ; when the jet is oblique to the confined wall , the cooling effectiveness is weaken especially under the jet - to - surface spacing ratio is greater than 2 ; for double rows normal impingement cooling , the cooling effectiveness of rear row jet is weaker than the front row under lower impinging reynolds number or bigger jet - to - surface spacing
對于單排垂直射流,沖擊冷卻效果隨射流雷諾數(shù)的增加、孔間距與直徑比的減小而得到提高,沖擊間距比為2時(shí)換熱效果最好;沖擊孔中心線向通道封閉一側(cè)傾斜后,射流沖擊冷卻的范圍變窄,當(dāng)沖擊間距比大于2時(shí)駐點(diǎn)區(qū)的對流換熱能力明顯降低;對于雙排沖擊射流,孔排間距與直徑比的增加使沖擊冷卻范圍變大,但在兩排孔之間區(qū)域的對流換熱系數(shù)有所下降;在較小的沖擊射流雷諾數(shù)和較大的沖擊間距比下,后排射流的沖擊換熱效果要遜于前排射流。
