Since double-suction centrifugal pumps consume quantities of energy. revealing critical factors for energy dissipation is helpful for energy-saving design. This study aims to investigate the relationship between energy dissipation and vortex based on Rortex method in a double-suction centrifugal pump. Detached eddy simulation was applied to obtain the flow field. https://ashleyshomestores.shop/product-category/swivel-accent-chair/
