velocity of entry
解釋
進入速度-
Firstly, simulate flow field of rear smoke channel, plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater, compare with data which were measured in guiyang power station, verify simulation to be reasonable and right. secondly, simulate all kinds of factors which affect flow field ' s uniformity such as length, thickness, location of diffluent board, ash concentration, ash diameter, and so on, find the chiefly factors. thirdly, install guide board in curve channel in rear smoke channel, then simulate its " flow field, plot velocity magnitude and ash concentration distribution
在此基礎上模擬在冬夏兩季不同情況下，不同流速對熱管空氣預熱器壁面溫度的影響；然後對影響整個流場分佈的各種因素：包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬；最後提出在分流煙道轉彎處加裝導流板，並模擬加裝導流板后的流場分佈，得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈，以論證加裝導流板能達到流場均勻化的作用。 -
First, proper way of gps positioning are selected according to the high dynamic flight characters of re - entry spacecrafts, such as high distance from the earth, high velocity and far awy from the launching point
本文首先根據再入航天器飛行高度高、速度快、飛行距離遠等特點，對gps定位方式進行選擇。 -
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。
