Performance comparison of jet pumps with round and sharp edge of small opening in oscillatory flow

•Effect of rounding on a jet pump is systematically investigated.•Jet pump with sharp edge induces reversed and higher time-averaged pressure drop.•A jet pump with rounding at small opening can work more efficiently.•The optimal taper angles for sharp and round edge jet pumps are different. Owing to...
