摘要
重点介绍了利用数值计算和 PIV技术对压力水槽中的射流流场速度分布进行测量 。
Oncomelania is middle-parasitizeder of Schistosome. Controlling the Oncomelania is the important way of preventing the schistosome. This article mainly introduces the measurement of jet flow field's velocity in pressure conduit by calculations and using high-tech particle image velocity(PIV), and analyses the reason why the oncomelania could sink to the bottom but not escape from the equipment named oncomelania-free intake devices.
