The performance benefits of deploying tidal turbines in close side-by-side proximity to exploit constructive interference effects are demonstrated experimentally using two 1.2 m diameter turbines. arrayed at 1/4 tip-to-tip spacing, and their compared with that a single rotor. Tests were completed the 25 diameter, 2 deep wave current FloWave Ocean Energy Research facility. A detailed assessment ...

Injection of biomass powders into multiphase reactors is a challenging task that may impact the process yield and limit operation due to feeder’s blockage or unstable flow. A horizontal pressurized gas-solid feeder characterized in this study inject batch different diameters cold-flow model operating under single phase, fixed fluidized regimes. The hydrodynamics injection line investigated for ...

The present paper aims to study the effect of partial blocking and flow regime on mutual turbulent interplay between porous non-porous regions in packed bed energy storage systems (PBESSs). To this end, high-fidelity pore-scale large eddy simulations (LES) are conducted for two PBESS configurations, namely full blockage under discharge process at three Re numbers 3600, 7200, 14,400. influences ...

We investigate stochastic models of particles entering a channel with a random time distribution. When the number of particles present in the channel exceeds a critical value N, a blockage occurs and the particle flux is definitively interrupted. By introducing an integral representation of the n-particle survival probabilities, we obtain exact expressions for the survival probability, the dist...

The ability of DNA to adopt non-canonical structures can affect transcription and has broad implications for genome functioning. We have recently reported that guanine-rich (G-rich) homopurine-homopyrimidine sequences cause significant blockage of transcription in vitro in a strictly orientation-dependent manner: when the G-rich strand serves as the non-template strand [Belotserkovskii et al. (...

Plaque morphology in a diseased coronary artery plays a significant role in the modification of the fluid flow characteristics. The plaque morphology of forty-two patients who underwent IVUS (intravascular ultrasound) procedure was quantified by degree of membership in four fuzzy logic sets, which we refer as type I: protruding, type II: ascending, type III: descending, and type IV: diffuse. Of...

Abstract. Recently, it has been shown that flow blockage in large wind farms may lift up the top of boundary layer, thereby triggering atmospheric gravity waves inversion layer and free atmosphere. These impose significant pressure gradients causing detrimental consequences terms a farm's efficiency. In current study, we investigate idea controlling farm order to mitigate efficiency drop due wi...
