Impurity convection reversal caused by edge localized turbulence for generating a stationary edge radiative layer in the HL-2A tokamak

Nuclear Fusion
The effect of impurity on edge turbulence was investigated on the HL-2A tokamak using neon supersonic molecular beam injection (SMBI). For the first time, a stationary radiative layer accompanied by edge localized turbulence (ELT) lasting more than 100 ...

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

Asia-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.

Two-particle dispersion in weakly turbulent thermal convection

New Journal of Physics, 2016
We present results from a numerical study of particle dispersion in the weakly nonlinear regime of Rayleigh–Bénard convection of a fluid with Prandtl number around unity, where bi-stability between ideal straight convection rolls and weak turbulence in ...

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 ...

How turbulence spreading improves power handling in quiescent high confinement fusion plasmas

Communications Physics
Viable magnetic fusion devices necessitate combining good confinement with effective power flux handling. A major concern for ITER, and devices beyond, is the divertor heat load width, which sets peak boundary heat loads on the plasma-facing materials ...

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.
