The maritime transportation of electric vehicles (EVs) poses significant fire risks due to the potential for thermal runaway in lithium-ion batteries, particularly when the state of charge (SOC) varies. This study uniquely examines the effects of SOC

Estuary reopening is a means of restoring estuarine habitats, which has recently been implemented in a few developed countries. The regeneration of a brackish zone in the Nakdong River Estuary (NRE), South Korea, were tested through a series of barra

Abstract In the present study, we introduce new bubble velocimetry methods based on the optical flow, which were validated (compared) with the conventional particle tracking velocimetry (PTV) for various gas–liquid two-phase flows. For the optical

The atomization of a water column by a gas jet flow (Reynolds number $\sim O(10^{4}\unicode{x2013}10^{5})$ ) issued from a two-stage annular nozzle is investigated experimentally. Varying the nozzle geometry, the momentum flux ratio of the upper and

Electroconvection (EC) near an ion-selective membrane has attracted significant attention in concentration polarization platform and been generally accepted as a cause of the overlimiting current. Especially, the heterogeneous structures of the ion-s

In the present study, we perform a series of water-tunnel experiments to investigate the flow around an in-line sphere array at the Reynolds number of 1000, based on the free-stream velocity and sphere diameter, focusing on how the sphere wake change
