Furthermore , the horseshoe shape vortex system occurred to the upstream of the jet exit and the layer structure of vortexes occurred to the wake of the reverse flow region downstream of the jet are also investigated 另外,觀測(cè)到射流噴口上流的馬蹄渦系以及射流逆流區(qū)下游尾跡區(qū)旋渦的層狀結(jié)構(gòu)形式。
Under different positions of a tripping wire or speeds of the side jet , the controlled experiments were made , including the receptivity of the shear layer near jet exit to acoustic excitations , the spatial development of fluctuating velocity and the profiles of mean velocity 在不同絆線位置或不同旁射流流速條件下,研究了射流出口臨近剪切層對(duì)聲激勵(lì)的感受性,脈動(dòng)流速向下游的空間演化及平均流速剖面。
According to rigorous procedures , an experimental study was carried out to investigate the effects of jet exit velocity , flow direction , fluid subcooling and nozzle diameter on hysteresis of boiling heat transfer with impinging circular submerged jets of highly - wetting liquids 摘要系統(tǒng)地研究了液體在圓形斷面噴嘴浸沒(méi)射流作用下沸騰熱滯后與射流沖擊速度大小、液體流動(dòng)方向、液體過(guò)冷度和噴嘴直徑等因素的影響。
The dual - time stepping method proposed by a . jameson is applied to improve time precision for unsteady flowfield computation . the three dimensional grid for projectile with lateral jets , especially body - fitted for lateral jets exit , is generated by improved traditional methods with projection and zonal method 在改進(jìn)傳統(tǒng)網(wǎng)格生成方法的基礎(chǔ)上,結(jié)合投影映射、分區(qū)拼接技術(shù)生成了彈丸側(cè)噴流場(chǎng)單一區(qū)域三維計(jì)算網(wǎng)格,在側(cè)噴流噴口邊界實(shí)現(xiàn)了網(wǎng)格貼體化。
Analysis indicates the " low pressure closed reticular flow region " results in the non - equilibrium of pressure along the primary jet ' s orifice . to obtain as large vectoring angle as possible , the optimal ranges of angles , frequencies , velocity amplitudes , and distances from the microjet actuator to the primary jet exit were discussed . the relationship between the vectoring angle of the primary jet and the phase - difference of two adjacent actuators was analyzed 分析了“拉”模型單作動(dòng)器模式下,微射流作動(dòng)器的入射角度、驅(qū)動(dòng)頻率、速度幅值及與主射流間的距離對(duì)主射流偏轉(zhuǎn)程度的影響,并確定了作動(dòng)器工作參數(shù)的最佳范圍;分析了“拉”模型雙作動(dòng)器模式下,不同的相位差對(duì)主流偏轉(zhuǎn)程度的影響。
