Abstract of the Disclosure Fluid Dynamic Pump A fluid dynamic pump, such as an ejector, has a common wall which separates a primary high energy fluid flow passage and a secondary low energy fluid flow passage. The common wall includes a plurality of adjoining lobes extending in the direction of flow to the outlets of the passages at the downstream end of the common wall. A lobe on one side of the wall forms a corresponding through on the other side. The common wall therefore has a wave-like shape at its downstream end. Primary and secondary fluid flow from the through outlets on their respective sides of the common wall and are mixed together rapidly in a mixing region downstream of the outlets. Secondary fluid is thereby drawn or pumped into the mixing region as a result of this transfer of energy from the primary stream to the secondary stream. Viscous losses are low during the process.
