Separating Mesoscale and Submesoscale Flows from Clustered Drifter Trajectories

Fluids, 2020
Drifters deployed in close proximity collectively provide a unique observational data set with which to separate mesoscale and submesoscale flows. In this paper we provide a principled approach for doing so by fitting observed velocities to a local ...

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

Asia-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

Asia-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 ...

Synchronized Multiple Drop Impacts into a Deep Pool

Fluids, 2019
Drop impacts (onto dry or wet surfaces or into deep pools) are important in a wide range of applications, and, consequently, many studies, both experimental and numerical, are available in the literature.

Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Tip Effect of the Tapping Mode of Atomic Force Microscope in Viscous Fluid Environments

Sensors, 2015
Atomic force microscope with applicable types of operation in a liquid environment is widely used to scan the contours of biological specimens. The contact mode of operation allows a tip to touch a specimen directly but sometimes it damages the specimen;

Structure Radio Beam Construction in Azimuthal Domain

IEEE Access, 2020
Structure radio beams with diverse radiation patterns exhibit huge potentials in many applications. In this paper, we propose a plane spiral orbital angular momentum (PS-OAM) based structure radio beam construction scheme, in which several PS-OAM waves ...
