Fine-Scale Structures in the Mid-Level Eyewall of Super Typhoon Rammasun (2014) Simulated With the WRF-LES Framework
Published in Frontiers in Earth Science
It has been numerically demonstrated that the turbulence above the boundary is important to tropical cyclone intensification and rapid intensification, but the three-dimensional structures of the sub-grid-scale (SGS) eddy have not been revealed due to the lack of observational data. In this study, two numerical simulations of Super Typhoon Rammasun...
In-vitro and In-Vivo Assessment of 4D Flow MRI Reynolds Stress Mapping for Pulsatile Blood Flow
Published in Frontiers in Bioengineering and Biotechnology
Imaging hemodynamics play an important role in the diagnosis of abnormal blood flow due to vascular and valvular diseases as well as in monitoring the recovery of normal blood flow after surgical or interventional treatment. Recently, characterization of turbulent blood flow using 4D flow magnetic resonance imaging (MRI) has been demonstrated by ut...
Wake flow and vortex structures behind emergent vegetation patches elongated in the longitudinal direction
Published in Journal of Hydrodynamics
In natural rivers, patches of vegetation generally expand over their steady wake region in the streamwise direction, forming elongated patches with length (L) greater than their width (b). This paper studies how the wake flows and the vortices develop as the emergent patches expand their length in the streamwise direction. The patches are modeled w...
Effect of sand mining on the flow hydrodynamics around an oblong bridge pier
Published in Engineering Research Express
Extraction of sand from riverbed has catastrophic repercussions on aquatic animalia habitat, water quality, and the environment. Alongside, physical alterations in the fluvial hydraulics arising on account of sand mining are also worthy of attention. Flows passing over the pits excavated in a channel have enhanced erosive propensity, which can be a...

Experimental Study of Hydrodynamic and Self-Buried Behavior of Submarine Pipeline with Perpendicular Spoilers
Published in China Ocean Engineering
The spoiler is a kind of device to disturb current and promote burying. At present, all submarine pipeline spoilers at home and abroad are parallel spoilers, that is, the plane of the spoiler is parallel to the vertical plane of the pipeline axis. According to the results of indoor experiments, when the pipeline with the forward spoiler is installe...
Computational fluid dynamics of rectangular external loop airlift reactor
Published in International Journal of Chemical Reactor Engineering
The novel design of a rectangular external loop airlift reactor is at present the most used large-scale reactor for microalgae culture. It has a unique future for a large surface to volume ratio for exposure of light radiation for photosynthesis reaction. The 3D simulations have been performed in rectangular EL-ALR. The Eulerian–Eulerian approach h...
Erosion of the nocturnal boundary layer in the central Amazon during the dry season
ABSTRACT In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (PArallelized Les Model - PALM). The dataset consisted of in situ (radiosonde) and remote sensing instruments measurements (Ceilomet...
Spatial and spectral investigation of turbulent kinetic energy in cavitating flow generated by Clark-Y hydrofoil
Published in Journal of Hydrodynamics
In the present paper, the turbulent cavitating flow generated by a Clark-Y hydrofoil is investigated by large eddy simulation (LES) combined with Zwart-Gerber-Belamri (ZGB) cavitation model. In order to shed light on the influence of cavitation on turbulent energy distribution among scales, energy spectrum obtained from the three-dimensional veloci...
