Aiming to mitigate impact of the uncertain boundary conditions setting on the underwater radiated noise calculation. the numerical prediction method of calculating the underwater radiated noise of a waterjet by the one-step boundary element method was explored. First. the transient flow field of the waterjet was calculated on the basis of Detached Eddy Simulation(DES). https://allfixelectricales.shop/product-category/sla-battery-charger/
