CHARACTERISTIC OF ECOLOGICAL FLOW FIELD IN AN ONCEMELANIA-FREE WATER INTAKE DEVICE

摘要

Oncemelania is middle-parasitizeder of Schistosome. Controlling the Oncomelania is the important way of preventing the Schistosome. This paper mainly introduces the measurement of jet flow field's velocity in pressure conduit by FVM numerical modeling and using high-tech particle image velocity (PIV), and analyses the reason why the Oncemelania could sink to the bottom but not escape from the equipment named Oncemelania-free intake devices.
