CONTROL OF FLUID DYNAMICS IN SPIRALING GAS STREAMS

摘要

Spin rate and volume flow rate of spiraling gas streams are regulated to control the fluid dynamics thereof. At constant supply pressure, either the spin rate or the volume flow rate of the spiraling stream can be changed without altering the other rate. Should the supply pressure change, both rates can be maintained constant. In addition, the spin rate can be increased even if the static pressure is lowered and can on the other hand be decreased if the static pressure is raised. These effects are accomplished by regulating the spin rate and the volume flow rate of a spiraling gas stream independently of one another.
