Experimental Investigation of Turbulence Specifications of Turbidity Currents

open access: yesJournal of Applied Fluid Mechanics, 2010
The present study investigates the turbulence characteristic of turbidity current experimentally. The three-dimensional Acoustic-Doppler Velocimeter (ADV) was used to measure the instantaneous velocity and characteristics of the turbulent flow.

All-Optical Turbulence Perception via a Coherence-Length- Sensitive Diffractive Processor

open access: yesApplied Sciences
Atmospheric turbulence originates from random fluctuations in the refractive index of the propagation medium that induce wavefront distortions and intensity scintillation.

Systems of intensive vertical vortices in turbulent atmosphere

open access: yes, 2019
At certain conditions a system of well-separated quasi-point vortices can appear in two-dimensional turbulence. Such system contains main part (almost entire) of the flow enstrophy (mean squared vorticity). Spectral properties of the two-dimensional turbulence in the presence of the system of the quasi-point vortices have been studied using notion of ...

Lost in aggregation? On the importance of local food price data for food poverty estimates

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Grid Independence Study and a Finite Difference Collocation Approach for Magnetized CeO2‐Ti3C2/H2O Hybrid Nanofluid Flow Over an Inclined Spinning Disk With Newtonian Heating

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines magnetohydrodynamic (CeO2, Ti3C2/H2O) hybrid nanofluid (HNF) flow on an inclined revolving disk with effects of Newtonian heating. HNF is obtained by suspending the nanoparticles (NPs) of CeO2 and Ti3C2 in water (H2O). The flow is affected by mixed convection, Joule heating, nonlinear thermally radiative and dissipative ...

Influence Mechanism of Structural Parameters of a Novel Sleeve‐Shaft Counterrotating Hydrodynamic Cavitation Reactor on Cavitation Characteristics and Performance

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...
