round nozzle 中文意思是什麼
round nozzle
解釋
圓截面噴管-
Simulation results show that better atomization can be realized by enhancing the cavitation intensity via increasing the injection pressure difference or decreasing the nozzle inlet round angle - radius ratio
通過模擬計算可知，提高噴射壓差和減小噴孔入口圓角半徑都可以提高空穴強度，同時也發現提高噴孔長徑比可以使空穴在噴孔出口截面上分佈更為均勻。 -
Based on this model, the effects of geometric and structural parameters, such as injection pressure, rear pressure, length - diameter ratio, inlet round angle - radius ratio and non - axis symmetry of nozzle, on the distribution of the cavitation inside the nozzle are analyzed
基於這一模型進一步分析了噴射壓力、背壓和噴孔長徑比、噴孔入口圓角比、非軸對稱噴孔等幾何結構參數對噴孔內空穴分佈的影響。 -
The results show that the more deeper the nozzle immersion depth is, the less the molten steel velocity at the interface, the weaker the oscillation near the interface and the more difficult the occurrence of the slag entrapment become. compared with the round entry nozzle, the rectangular entry nozzle can reduce the occurrence of the slag entrapment
結果表明:採用較大的水口浸入深度可以減小表面速度，抑制液面波動，避免鋼渣卷混的產生;與圓形水口相比，長方形水口能有效地減小卷渣發生的可能性。 -
Through tests of different nozzle - equipped emergency ventilation systems, the authors hold that, under the same condition of air volume and air pressure, the round mouth nozzle and its parameters is the best, thus provides reference for the design of emergency ventilation system
對不同類型噴口的通風系統性能進行了試驗，提出在相同的風量和風壓下，橢圓噴口的通風功能和防災能力最強，噴口出口風速提高有利於提高其風量效率等結論，為隧道事故通風系統提供了設計依據。
