Mechanical Engineering Fluid mechanics

Logically, you would think a sleek surface has optimal aerodynamics – but recent research at Tohoku University turns this fundamental principle completely on its head. Applying an irregular microscale surface texture reduced the aerodynamic drag of a test model. The innovation has potential applications for designing fuel-efficient vehicles.

Dr. Zhang Yi, the lead scientist, and his team of researchers from Canada, Singapore, the UK, have successfully completed a study, comparing the efficiency of various bioreactors in producing Raspberry Ketone through Submerged Fermentation. This research marks the first time such a study has been conducted.

Theoretical simulations reveal how small amounts of friction on an object’s surface can trigger drag-reducing eddy currents.
