中文摘要 | 在本文中,提出由一移動平板皮流動冪次律流體之流動和熱傳送分析。文中提議用一相對速度作為一控制參數,它可以決定平板速度和自由流動速度間之相關大小。進一步將座標及應變數作一轉換以得到一相當有效的數值解,這數學解可以適用於整個對流熱傳遞區域,從一冪次律自由流體流過一靜止平板(γ=1)中運動。相對速度參數、冪次律黏性指數及普朗特數對於速度輪廓、溫度分佈及熱傳遞等之影響在文中都作了清楚地說明。 |
英文摘要 | The analysis of flow and thermal transport from a flat plate moving through flowing power-law fluids is presented. A relative velocity parameter is proposed to serve as a controlling parameter that determines the relative magnitude of the velocity of plate and the free stream velocity. Furthermore, the coordinates and dependent variables are transformed to yield computationally efficient numerical solutions that are valid over the entire regime of convective heat transfer from a power-law fluid free stream flowing over a stationary flat plate (γ=0) to a moving flat plate in a quiescent power-law fluid (γ=1). The effects of the relative velocity parameter, the power-law viscosity index and the generalized Prandtl number on the velocity profiles, the temperature distributions and the heat transfer rates are clearly illustrated. |
