Abstract

Abstract

En 中文
• Detailed DNS study in co-current stratified flow with focus on near interface turbulence. • Solve stratified flow with DNS using second-order finite-volume-based approach. • Turbulence shear production is enhanced while wave amplitude decreases with film height. • Rough wall similitude of gas-liquid interface in stratified flow is not universally valid.
