本文之主要目的在於用數值方法來模擬計算分析密閉矩形室流場及熱傳現象。在有黏滯性之不可壓縮流場中,研究其密閉矩形室之不同開口之幾何設計對流場及熱場之影響。本文採用商業套裝軟體FLUENT,其數值方法選擇SIMPLEC來進行模擬計算。
物理模型以高溫氣體流入只有出入口之矩形室,而其開口之幾何設計首先以單入口單出口作測試,觀察其流場及熱場之現象,接著再以多入口單出口測試其流場穩定度及熱場溫度分布,最後以多入口多出口去測試,討論其出入口之幾何設置對其流場穩定性和熱場溫度散佈之關係。
計算結果再以其所定義測試區域了解不同幾何設計對其不同大小之測試區域內溫度散佈之影響及其熱場性能,也可以發現在有入口高度差和多出口其性能較佳。
This paper studies the behaviors of laminar flow and heat transfer in an open enclosure regular chamber.The software, FLUENT(Copyright (c) 2004 Fluent Inc.) is used to simulate the flow fields.Here the SIMPLEC algorithm is chosen in this software.
The physical model is that high temperature gas enters into the enclosure chamber.We want to investigate the fluid field and temperature distribution in the chamber. Three different geometry configulations ,single inlet to single oulet,two inlet to single outlet,and two inlet to three-oulet are chosen.
The uniformity and stability of flow field and temperature distribution are investigated for these cases.Two inlet to two outlet has better performance in these cases.
