Abstract :

Ejectors Are Devices Often Used In Aircraft Systems. They Typically Have A Main Tube That Ends In A Nozzle, Which Is Usually Either Converging Or Converging-diverging In Shape. In This Study, We Focus On Improving How Well These Ejectors Work. The Main Goal Is To See If Changing The Nozzle From A Simple Converging Shape To A Converging-diverging Shape Can Make The Ejector More Efficient And Easier To Control. To Find Out, We Used Ansys Fluent Software To Analyze The Airflow Through The Ejector. We Looked At How Pressure, Temperature, And Speed Change Inside It. The Results Showed That Using A Convergingdiverging Nozzle Increases The Mass Flow Ratio, Which Means Better Performance, Compared To The Regular Converging Nozzle, All Based On The Same Size And Shape. Keywords: Nozzle, Ejector, Primary Flow, Secondary Flow, Mass Augmentation Ratio.
