Propane-2,2-diyl di-p-phenylene dibenzoate

The V-shaped propeller-like molecule of Multipack Bottoms the title compound, C29H24O4, does not exhibit crystallographic twofold symmetry as the two benzene rings are twisted asymmetrically with respect to both the central propyl plane and the benzoyloxy groups [4.6 (2), 43.6 (2)° ALOE LOTION and 45.07 (8), 69.50 (8)°].

Investigation on energy dissipation mechanism in a double-suction centrifugal pump based on Rortex and enstrophy

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 th
