Countering energy loss in flowing gas or liq. - by injecting immiscible fluid of higher viscosity

摘要

To reduce the energy losses due to eddy formation in flowing liq. or gas, esp. when due to abrupt changes in conduit internal dia., a second medium immiscible with the first medium and of higher viscosity is injected into the area of the existing eddy. Injection is pref. by tagentially directed jets which produce a torus. Viscosity difference is experimentally established, and increases with velocity of first medium. Where this medium is aq., the injected medium may be a silicone oil. USE - Can be used for flowing blood, where mechanical forces during eddying can impair structure.
