Effects of preform structure on mechanical properties of carbon - carbon composite for nozzle exit cone 噴管出口錐材料力學(xué)性能的影響
Uniform distribution of cavitation at the nozzle exit section is obtained by increasing length - diameter ratio and leads to the improvement of atomization 從燃油空穴霧化理論的角度出發(fā),空穴強(qiáng)度的提高以及在出口截面上的均勻分布都有利于燃油的破碎霧化。
The experimental results show that the location of the diffuser should be close to the nozzle exit , and the shape and size of the diffuser entrance should match the nozzle exit 實(shí)驗(yàn)表明,擴(kuò)壓段應(yīng)安裝在距主噴管較近的位置,并具有與主噴管相匹配的入口面積和形狀。
The conclusion that the optimal secondary nozzle exit area generating the maximum thrust agrees well with the numerical simulation , indicating that the exit area of secondary nozzle should be optimized according to structure and flow parameters during design 表明在引射火箭設(shè)計(jì)時(shí),應(yīng)結(jié)合引射火箭的結(jié)構(gòu)和流動(dòng)參數(shù)對(duì)二次噴管出口面積進(jìn)行優(yōu)化設(shè)計(jì),以達(dá)到最佳推力性能。
The energy equation of the thrust chamber wall was developed by omitting radical heat conduction and only considering the radiation heat transfer of the four chambers , the radiation leakage through nozzle exit , the axial and circular heat conduction 忽略徑向?qū)幔紤]推力室外向的相互及自身輻射交換、內(nèi)壁經(jīng)噴口的輻射泄漏以及周向和軸向的傳導(dǎo)熱量,建立了推力室壁的能量方程。
The ratio of mach number between lateral jet and free flow induce intensity degree of jet interaction . it has no obvious difference between two interactions with two types of nozzle exit configuration , rectangle and ellipse . the shock in front of jet results in increase of shock resistance and the jet ejection causes increase of base resistance 研究表明,側(cè)噴流與來流馬赫數(shù)之比是影響繞流場(chǎng)的重要因素,該值越大則側(cè)噴干擾越強(qiáng)烈,矩形和橢圓形兩種側(cè)噴口形狀對(duì)側(cè)噴流場(chǎng)干擾波系的影響并不明顯。
Abstract : optimum distances between primary nozzle exit and mixing tube inlet , static pressure recovery of the mixing flow in mixing tube 、 total pressure distributions at the exit of mixing tube 、 pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments 文摘:對(duì)4種主噴管組成的排氣引射系統(tǒng)的引射系數(shù)和總壓損失、各主噴管出口與混合管進(jìn)口之間的最佳間距、混合氣流在混合管內(nèi)的靜壓恢復(fù)及混合氣流在混合管出口處的總壓分布等進(jìn)行了測(cè)量和對(duì)比。
