摘要對(duì)g4135直噴式柴油機(jī)建立了一個(gè)輻射多區(qū)多維模型，包括缸內(nèi)工質(zhì)的幾何空間模型、輻射溫度模型、輻射發(fā)射系數(shù)、吸收系數(shù)以及燃料油滴的散射系數(shù)模型。 - A multizone p - pdf is applied to calculate the instantaneous rate of no _ ( x ) with high turbulent conditions in the lpg engine . 4 . construct an experimental spark - ignited premixed - charge lpg single fuel engine with universal wide range exhaust gas oxygen sensor
4建立稀氧傳感器反饋控制的lpg發(fā)動(dòng)機(jī)實(shí)驗(yàn)系統(tǒng)，準(zhǔn)確控制發(fā)動(dòng)機(jī)的實(shí)驗(yàn)參數(shù)和工況，得到不同空燃比、不同點(diǎn)火提前角、不同燃料成分時(shí)發(fā)動(dòng)機(jī)的動(dòng)力性能和排放性能。 - Second , a parallel adaptive ray - casting algorithm for graphic rendering of cfi is developed . in the computational model of cfi , the line - of - sight integration is difficult to obtain for 3d complicated flow field , because curvilinear grids , multizone curvilinear grids , and other irregular grids that are commonly used in computational fluid dynamics ( cfd ) present interesting challenges , such as the complex shapes of cell regions defined by grid points ; the wide variation in the sizes of cells in different regions of the grid ; and the intersecting or overlapping nature of multi - grids . the parallel adaptive ray - casting algorithm is extremely efficient to solve these problems
并行自適應(yīng)光線投射法繼承了光線投射法適合于任何形式網(wǎng)格的優(yōu)點(diǎn)；光線與計(jì)算網(wǎng)格的交點(diǎn)自適應(yīng)地反映了原來網(wǎng)格點(diǎn)物理量的分布，能夠與數(shù)值計(jì)算的精度保持一致；圖像平面的自適應(yīng)算法使我們不必從每一個(gè)像素發(fā)出射線，既提高了光線投射法的計(jì)算效率，同時(shí)又保證重采樣后激波這樣的高頻信息不會(huì)損失；將并行處理技術(shù)引入計(jì)算光學(xué)流動(dòng)圖像生成過程，解決了大規(guī)模數(shù)值模擬結(jié)果的處理對(duì)計(jì)算速度和內(nèi)存容量的需求。
