中文拼音 [líxīnjiāhòu]
離心加厚
英文
centrifugal thickening-
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。When the width of the foundation is smaller, the friction force is firstly increased from zero at the central area of the foundation, then decreased to zero at the edges of the foundation, hence there is a peak ; when the width of the foundation and the thickness of the soft ground is larger, the frication force is almost zero from the central area of the foundation to a certain distance, then increased, at last decreased to zero at the edges of the foundation, therefore there is a peak ; and when the width of the foundation is larger and the thickness of the soft ground is smaller, the friction force is firstly increased from zero at the central area of the foundation in the negative direction, then decreased to zero, so there is a negative peak, then increases in the positive direction, eventually decreased to zero at the edges of the foundation, hence there is a positive peak
當基礎寬度較小時，從中心線為零處開始增加，達到峰值后，開始減小，直至基底邊緣處為零；當基礎寬度和軟土地基厚度較大時，從中心線處開始，向外側延伸一定距離，幾乎為零，然後開始增加，達到峰值后，開始減小，直至基底邊緣處為零；當基礎寬度較大，並且軟土地基厚度較小時，從中心線為零處開始反向增加，達到反向峰值后，然後反向減小，減小到零后，逐漸正向增加，達到峰值后，再逐漸減小，直至基底邊緣處為零。The method takes advantage of bezier curve to work out a set of blade profiles of centrifugal pump, using thickening law to thicken the profiles. then the pressure and suction lines of the blade can be obtained. it takes advantage of bezier surface to create pressure and suction surface and makes use of mdt software to create the three - dimensional blade entity
首先採用速度系數法計算得到離心泵葉輪的基本參數，再由b zier曲線生成一組葉輪葉片型線，按照加厚原理對型線進行加厚，得到正背葉片線，再採用張量積b zier曲面生成葉片正背面，由mdt進行三維實體造型得到葉片，從而得到流場計算區域的模型。
