To improve the design speed and reduce cost for previous blade method, a modified inverse method is presented. In new after series of physical mathematical simplifications, sail-like constrained area proposed, which can be used to configure different runner shapes. Then, applied redesign optimize scale core component 1400-MW canned nuclear coolant pump in an established multi-optimization system compromising Computational Fluid Dynamics (CFD) analysis, Response Surface Methodology (RSM)...
Due to the higher propulsive efficiency, lesser vibration, and better maneuverability, water jet pump is widely applied high-speed underwater vehicles. By taking a newly developed system as object, corresponding vehicle’s operating characteristics affected by different cruising speeds (15.43, 30.86, 52.47 m/s) were investigated. The steady results reply that speed increase will result in decline of overall performances comprised head, thrust, power. While, using analyzing methods, unsteady...
