Upgrading vortex amplifier performance by matched ejectors
Abstract
The use of a matched ejector or jet pump is shown to be beneficial in the design of a vortex amplifier with low control pressure requirements. By entraining fluid from a low pressure source to be used as control flow for the amplifier, a correctly matched ejector can increase the turndown ratio by a factor of more than ten. Results are presented for tests on a vortex amplifier and ejector combination using both air and water as the working fluids. A practical system is designed to illustrate the principle.
