摘要：
In this paper, a desilting jet pump with low disturbance was designed based on hydromechanics Coanda effect. The performance of the desilting jet pump was evaluated by computational fluid dynamics (CFD) technique. The sensitivity of design parameters to dredging performance and the interaction between the parameters were analyzed by using the experimental design method. The sensitive parameters affecting the bottom scour momentum and work efficiency are the bottom distance and the exit radius, and the coupling effects between the design parameters are also significant. The response surface model of design parameters and performance was further established. The optimal results were obtained by the optimization algorithm. The bottom scour momentum and operation efficiency of the optimal scheme are 8.05 m4/s2 and 32.1% respectively, higher than those of other cases in the experimental design. The results show that the response surface model method is effective for parameter optimization of desilting jet pump suction heads. © 2022, Editorial Board of Journal of Ship Mechanics.
