droplet transfer 中文意思是什麼
droplet transfer
解釋
熔滴過渡作用-
Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high
通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析，得到：撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角，噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高，撞針型結構提高了霧化加濕效率，高壓小孔徑的特點為霧化加濕提供了較大的能量，而噴水初溫的升高會減小水的粘性力和表面張力，從而優化加濕效果。 -
As to the simulation, three - dimensional n - s equations and two - phase flow model, in which the liquid toluene spray as discrete particles was considered, were employed to describe the turbulent combustion processes in the combustion chamber. the mass and energy transfer between the two phases were calculated by the droplet evaporation model, and the arrehnius model was used to obtain the gas chemical reaction rate. the details of 3d flow field, the distributions of temperature and compounds were obtained by solving the equations
數值模擬方面，應用三維湍流n - s方程以及顆粒軌道模型描述了激光器燃燒室內部的噴霧兩相燃燒流動過程，兩相之間的質量、能量交換由液滴蒸發模型計算，氣相化學反應速率由arrhnius公式計算，通過耦合求解氣液兩相模型方程，模擬了燃燒室三維流場，得到了燃燒室內的溫度和組分濃度分佈。 -
One droplet per pulse transfer in gmaw - p is the most favorable transfer mode because of its high welding quality
在gmaw - p焊中，一脈一滴過渡形式因其焊接質量好得到了大家的普遍接受。 -
Randomicity amp; stability of short - circuiting droplet transfer in arc welding process
弧焊短路過渡過程的隨機性與穩定性 -
Mass transfer of micro droplet instantaneously accelerated by high - speed gas stream
高速氣流加速下霧粒的傳質 -
Besides its impact in the formation of the first raindrops by autoconversion, the prediction of cloud - droplet number concentration is especially important in cloud chemistry and radiative transfer
除了對初始自動轉化形成降水的作用外，雲滴數濃度的預報對雲化學和輻射傳輸有特別重要的意義。
