Energy Science &Engineering, EarlyView.Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Exploration, EarlyView.Inspired by the germination of probiotic spores, we utilize the excellent characteristics of spores to break through multiple barriers of oral brain‐targeted delivery. Besides the probiotics mediated gut‐brain communication, the spore coat proteins derived nanosystems with multiple‐barriers‐crossing ability alleviate neurodegeneration.

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...
