At the same time, the mathematical models of the electric field and the flow field distribution were established from the theory of electrostatic enhancement of heat transfer. employed finite differential method and over - relaxation iteration method, according to certain boundary conditions in the wire - plate electrode space, the electric field and the flow field in the wire - plate space were numerically simulated under different initial velocities of r11 stream and different magnitudes of applied voltage. the calculation results agreed with theoretical analysis satisfactorily
同時從靜電強化換熱理論出發,建立了表徵線板電極間的電場和流場分佈的數學模型,並根據線-板電極間的邊界條件,利用有限差分法和超鬆弛迭代法,分別就不同氣流初速度和不同外施電壓的情況下,對線-板空間的電場和流場進行了數值模擬,計算結果與理論分析基本一致。The performance of state - of - the art silicon pin diodes is now approaching the theoretical limits, and it is apparent that further advances in silicon technology are very difficult because of material properties
傳統的sipin功率二極體由於si材料特性的局限性,很難實現開關速度、通態壓降和反向漏電流三者良好的折衷。Based on the experience of regulating frequency according to different valve ' s angle, a reasonable controlling tactic is proposed. when the situation changes to a small degree, electromotor makes fan running at a constant rate ; when the situation changes to the limiting range, the discharge header pressure is automatically adjusted by the rate of fan
制定合理的控制策略,採用基於閥門開度的變頻調節策略,即工況變化較小的情況下,電機帶動鼓風機恆速運行,通過控制閥門開度自動調節集氣管壓力;當閥門開度到達極限值,還不能達到控制要求時,再通過變頻器改變鼓風機轉速,以自動調節集氣管壓力。
