摘要

日常生活中具有半透明介質的空間種類繁多，最常見的例子為房屋、汽車等等，這些都具有透明或半透明的窗戶。臺灣地處亞熱帶，四季如春，夏季尤其炎熱，經由太陽輻射照射，即造成密閉空間內溫度升高形成溫室效應。這種效應可應用的範圍廣泛，從節能到發電、日常生活上到農產品加工，都能見到應用的例子。
本研究利用一簡單模型，以燈光取代太陽為固定加熱源，在三種不同角度照射下，分別取得模型內部溫度變化、分佈的數據。再利用計算流體力學( Computational Fluid Dynamic, CFD )模擬模型受熱過程，分析模型內部氣體加熱後流動的情形，用以解釋空間內部溫度分佈的狀況。

The space with semi-transparent medium is various in style in daily life, the most common example is house, car,etc., all these have transparent or semitransparent windows. Taiwan is located in the subtropical zone, it's like spring all the year round, it is especially hot in summer, shine via solar radiation, cause the temperature in the airtight space to raise the greenhouse effects of taking shape. This kind of effect is applicable and in extensive range, from energy-conservation to generating electricity, daily to the processing of farm products in life, can see the example employed.
This research utilizes a simple model, regard replacing the sun in light as and heat the source fixedly, under the circumstances that three kinds of different angles shine, make the data that temperature changes, distributes within models separately. And then utilize and calculate hydrodynamics (Computational Fluid Dynamic, CFD) The simulation model is heated the course, analyze the situation of flowing within models after the gas is heated, in order to explain the state of the temperature profile within the space..
