本研究採用Patankar之冪次律法則(Power Law Scheme)，並採用MSIMPLEC法則做為數值計算法則，來模擬分析台灣電力公司通霄電廠汽機廠房內流場及散熱效果。本文固定出風口之大小、位置及進風口大小，而改變進風口的位置進行數值模擬，由數值模擬所得結果分析發現，當相對壁面的兩個進風口分別位於熱源之上、下方位置時，則流場的散熱量較多，熱源周圍平均溫度較低，冷卻效果較佳。

This study used Patanker's Power Law Scheme and MSIMPLEC method to simulate and analyze the flow field and heat dissipation inside the room of steam turbine in Ton-Shau power plant of Taiwan Power Company. The size and location of outlet openings, and the size of inlet openings are fixed, but several different locations of inlet openings are selected for the purposes of analysis. The analysis from the results, shows that when one opening located above the heat source, and the other one on the opposite wall located below the heat source, this can increase the heat dissipation, lower the average temperature around the heat source, and is the case with better cooling effect.
