Experimental results for various quench conditions revealed that the breakdown voltage of LN2 with increasing the bubble size, flow velocity and electrode distance.
Simulation of computational fluid dynamics showed faster water velocity near electrode modules and better sludge expansion in HAR-BES than AR.
The effects of fluid velocity and electrode spacing on oxidation rate were evaluated by determining the mass transfer coefficient and the effectiveness factor Ω (between 0 and 1).
COD removal efficiency, sludge settling velocity (SSV), electrode consumption and energy consumption under the optimum conditions were measured, which were 40%, 0.004 cm/min, 1.3 kg/m3 and 7.64 kWh/m3, respectively.
Porous carbon air electrodes have been operated in fully developed and laminar channel flow and their limiting current density measured with variations in the air velocity, the electrode length and the air channel thickness.
Indeed, the power depends on the ring diameter because the effective wetting dewetting period is decreasing with the increase in the linear sliding velocity for the electrode pattern with the fixed electrode strip width.
This work derives a new diffusion equation, which takes account of the effect of the local velocity in an electrode, to describe the migration of lithium in the electrode.
A complete design experiment strategy has been used to correlate fluid flow properties with classical factors like viscosity, rotation velocity and inner electrode diameter, and also with the axial position along the inner rotating electrode.
The lower velocity in the electrode will cause the higher overpotential, further result in the side reaction and corrosion of key materials locally.
It is shown that the distribution of the electrolyte velocity in the electrode has significant impact on the distribution of concentration, overpotential and transfer current density.
