We experimentally study heat transport in a gelatin solution near a reversible sol-gel transition point where viscosity strongly depends on temperature. We visualize the temperature field and velocity field using thermochromic liquid crystals and polystyrene latex particles, respectively. During the initial stages of heating, we find that heat transport undergoes a dynamical transition from con...

This study investigated the influence of stratospheric quasi-biennial oscillation (QBO) on tropical easterly jet (TEJ), using ERA5 and QBO series Singapore Freie Universität Berlin. Since 1980s, easterlies TEJ over Maritime Continent are weaker during (EQBO) than westerly QBO. influences by affecting convection east west sides Continent. The climatological rising movement side can reach a highe...

The indoor airflow with a mixed natural/forced convection was numerically calculated using the laminar and turbulent approach. The Boussinesq approximation was considered for a simplification of the mathematical model and calculations. The results obtained, such as mean velocity fields, were successfully compared with experimental PIV flow visualizations. The effect of the distance between the ...

Abstract Mass transfer rates at liquid–liquid interfaces are relevant for a broad range of processes in natural and technical systems. The objective this study was to characterize quantify convective flow along the interface between water nonaqueous‐phase liquids (NAPLs). Three NAPLs with different solubility were used: 1‐heptanol, 1‐octanol, 1‐nonanol. visualized recorded micromodel setup fluo...
