摘要
基于高等数学中值定理,提出了空调风管中风速测定的一种新方法。与CFD分析相结合,找出风管测量截面内风速值与平均风速相等的位置点,利用热线风速仪一次性测出风管内的风速。旨在减少风速测量中的重复性操作,缩短测量时间。
Based on the mean value theorem of higher mathematics,presents a new method for measuring air speed in ducts.Combined with the CFD analysis,finds the position point in the air duct measurement section where the air speed value is equal to the average air speed value,and measures the air speed at one time by hot wire anemometer.Puts forward the method to reduce repetitive actions in air speed measurements and shorten measurement time as well.
