火焰熱傳遞 的英文怎麼說
中文拼音 [huǒyànrèzhuàndì]
火焰熱傳遞
英文
flame heat tra fer-
Abstract : during the reduction of iron ore - coal pellet in air, the combustible gas generated from the reduction in pellet is burnt onto the firing surface around the pellet. between the pellet surface and the firing surface, ther e is such mixing gas containing the combudstible gas and burnt gas. it m ay b e sure that the iron ore - coal pellet is no oxidized in the week oxidizing atmos phere. the heat released by combusition on the firing surface is fast tranfered i nto the pellet, and the self - heating reduction of iron ore - coal pellet may occu r
文摘:鐵礦-煤球團在空氣中能夠還原的原因是：從球團排出的可燃性氣體在球面附近的火焰面上燃燒，在火焰面內側是氧化性較弱的可燃性氣體和燃燒產物的混合物，鐵礦-煤球團在弱氧化性氣氛中具有抗氧化性；在火焰面燃燒放出的熱量向球團傳遞，進行自熱還原Abstract : a numerical model and experiments over pmma are used to evaluate the main assumptions used in the theoretical description of a diffusion flame established in a natural boundary layer. flow characteristics ( 2 - d boundary layer ) and surface thermal balance are identified as the critical assumptions to be evaluated. comparison of experiments, numerical results, and theoretical model serve to validate the assumptions leading to the definition of a mass transfer number but establish the need to model all three - dimensional features of the flow
文摘:對pmma進行數字模擬和試驗，對描述自然邊界層擴散火焰理論的假設進行評價.我們把流動特性（二維邊界層）和表面熱平衡作為評價的關鍵假設.試驗、數字模擬和理論模型證實了對質量傳遞數值定義的假設是正確的，但研究也表明，有必要對流動特性進行三維模擬Protective clothing - protection against heat and fire - method for determining heat transmission on exposure to flame
