CFD Simulation and PIV Measurement of Local Fluid Velocity Distribution of Newtonian and Highly Shear-Thinning Fluid in an Impeller Rotational Region Open
Multistage impellers are widely used in the chemical industry to enhance the mixing of shear-thinning fluids. However, the local velocity around multistage impellers has not been sufficiently investigated. This study investigated the mixin…

Measurement Methods on Electrodes and Electrocatalysts for Water Electrolysis Open
Toward decarbonized society with sustainable growth, the use of renewable energy as a primary power source is highly demanded. Water electrolysis is promising to produce hydrogen from renewable energy for energy storage and transportation.…
Faster R-CNN-based Detection and Tracking of Hydrogen and Oxygen Bubbles in Alkaline Water Electrolysis Open
In this study, a method for detecting and tracking hydrogen and oxygen bubbles during alkaline water electrolysis was developed using Faster R-CNN and DeepSORT. The images required for CNN training were automatically generated by a pseudo-…
Experimental Investigation of the Power Consumption and Metzner–Otto Constant for Highly Shear-Thinning Fluids with Different Impeller Geometries Open
Common industrial non-Newtonian fluids are pseudoplastics with shear-thinning properties. During mixing, it is challenging to evaluate the power consumption for these fluids because the apparent viscosity (ηa), which is needed for the eval…
Relationship between bubble generation behavior and hydrogen evolution reaction performance at high current densities during alkaline water electrolysis Open
Alkaline water electrolysis (AWE) has attracted considerable attention in recent years as a means to produce hydrogen. However, one problem associated with AWE is the increase in overpotential at high current densities, which is attributed…
