Turbulent flow interacting with flexible trawl net structure including simulation catch in flume tank

open access: yesScientific Reports, 2023
The interaction between fluid and the midwater trawl with stocked catches is extremely complex, but essential to improve the understanding of the drag force acting on the trawl, the behavior of the fishing structure during a trawling process, and to ...

Vane Angle Influence on the Flow Pattern around a Circular Pier

open access: yesU.Porto Journal of Engineering, 2022
This paper intends to numerically analyze the hydrodynamic characteristics of the flow pattern that surrounds the circular pier near the vane angle. These include flow velocity, turbulent intensity, and pressure. A computational fluid dynamic is proposed

Experimental research on flow regime and transitional criterion of slug to churn-turbulent and churn-turbulent to annular flow in rectangular channels

open access: yesNuclear Engineering and Technology, 2023
As for two-phase flow in rectangular channels, the flow regimes especially like churn-turbulent and annular flow are significant for the physical problem like Countercurrent Flow Limitation (CCFL).
