應用SolidWorks Flow Simulation進行溫室內循環風扇流場分析之研究

In recent years, greenhouse is widely used to grow crop in Taiwan, and the main problem is the high temperature and humidity inside the greenhouse causing the crop physiological disorder, which influence the crop growth and decrease the yield. A conventional method is by drawing a great deal of external air into greenhouse to improve the climate, but in the case of suspend ventilation, the stationary air can cause harmful effect on crop. Keeping air circulating will be a great benefit to the crop. In order to reasch a circulating ventilation effectively, it is important to deploy the circulation fans appropriately. The ventilation capacity, deployment and the space of greenhouse influence the structure of flow field. Because the movement of air in the greenhouse is not easy to detect, it is hard to estimate the effects of air circulation. This research used SolidWorks Flow Simulation software to analyze the flow field on three different cases of greenhouses, the results of flow field analysis displays on a graphic interface which provides a great benefit to research on the air movement in greenhouse.
