HIGH-EFFICIENCY FLOW INDUCTION

THE PROPOSED INNOVATION IS A METHOD FOR IMPROVING THE ENERGY TRANSFER EFFICIENCY OF "DIRECT FLOW INDUCTION" PROCESSES THROUGH ENHANCEMENT OF THEIR SINGLE NONDISSIPATIVECOMPONENT, WHICH IS THE WORK OF INTERFACE PRESSURE FORCES. THIS IS ACHIEVED BY IMPARTING A TRANSVERSE MOTION TO PADDLE-LIKE JETS OF THE ENERGIZING FLUID, WITHOUT, HOWEVER, IMPARTING THE SAME MOTION TO THE FLUID PARTICLES THAT MAKE UP THE JETS THEMSELVES, HENCE AT NO ENERGY COST EXCEPT FOR FRICTIONAL LOSSES. THE TRANSFER OF MOMENTUM AND ENERGY FROMTHESE "FLUID PADDLES" TO THE FLOW TO BE INDUCED WILL TAKE PLACE IN GOOD PART THROUGH THE WORK OF THE PRESSURE FORCES THAT THE TWO FLOWS EXERT ON ONE ANOTHER AT THEIR MOVING INTERFACES. USE OF THIS MECHANISM CAN BE EXPECTED TO LEAD TO THE DEVELOPMENT OF IMPROVED JET PUMPS AND THRUST- OR LIFT-AUGMENTING EJECTORS.
