At the same time, differen t arrays of electrodes have been studied. flow visualization has shown that the plasma between symmetric streamwise electrode strips ca n ' t induce flow velocity at the same phrase driving but can at multi - phrase driving, and asymmetric streamwise eledtrode strips can induce flow velocity both at the same phrase and at multi - phrase driving in still air. in principle, the experimental results correspond to that of the cooperant research between university of tennessee and nasa langley research center
流動顯示實驗表明,在一個大氣壓下,對于電極對稱分佈的情況,在同相位的射頻激勵下,靜止的空氣中沒有明顯的現象,而在多相位射頻激勵下,靜止空氣中的二維平板上可以產生推力,誘導了流場;對于電極的非對稱分佈的情況,在同相位或多相位的射頻激勵下,都能在二維平板上產生推力,並誘導流場。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。The research object of this thesis is a chip - array that is fixed on one of printed circuit boards ( pcb ), which are located in a forced air field ( forced convection ) in an electronic case ; and from the essential equations of airflow we can deduce the mathematical model of the turbulent flow ; then we can establish the finite element algorithm and apply the fe software to work out the equations of turbulent flow, finally we can use the software to display and analyse the field of flow and temperature
本文以處于強迫空氣對流流場中的某pcb板及其板上的電子元件陣列作為研究對象,推導了紊流流場的數學模型,並建立了相應的有限元求解格式,應用有限元法分析軟體對該系統的紊流流場和溫度場進行了模擬分析:解算出pcb板上各電子元件的溫度分佈;並提出了用於求解系統風道特性曲線的cfd方法。Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove. the influence of differential horizontal plates on the distribution of cooling air is discussed. the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow, at the same time, is increased by horizontal plates. there is a different function with horizontal plates and vertical plates. to make the uniform distribution of cooling air in the hot air stove, it is necessary that horizontal plates and vertical plates are used in a combined way
文摘:應用紊流三維數學模型模擬內燃式熱風爐內冷風在格子磚柱中的分佈,尋求改善其分佈的途徑.討論了加設不同布置的水平導流板對氣流分佈的影響.模擬結果表明,在支柱空腔內加設水平導流板改變了原有大迴旋流場,使迴旋流變成大面積的單向流.通過在支柱空腔內加設水平導流板可以發展邊緣氣流,這恰好與加設豎直導流板的作用相反,水平導流板和豎直導流板的結合使用有望實現冷風在格子磚柱中的均勻分佈The impact broke open a heat panel on the wing, which allowed superheated gases to get inside the structure as columbia soared through the skies for landing 16 days later
