Development and validation of an enhanced filtered drag model for simulating gas-solid fluidization of Geldart A particles in all flow regimes

TL;DR: In this paper, an enhanced filtered drag model along with other different drag models derived from different methods for three-dimensional two-fluid model simulations of gas-solid fluidized beds of Geldart A particles covering a broad range of fluidization regimes.
Journal ArticleDOI

A fundamental CFD study of the gas–solid flow field in fluidized bed polymerization reactors

TL;DR: Wang et al. as discussed by the authors proposed a method to solve the problem of energy-efficient energy management in China's National Natural Science Foundation of China (NNSCF) and National Petroleum Corporation (CNPC).
Journal ArticleDOI

Experimental and numerical investigation of solid behavior in a gas–solid turbulent fluidized bed

TL;DR: In this article, a modified drag model was proposed using a scaling factor to reduce the universal drag laws, which accounts for the effect of particle clustering, and the simulated axial bed void and radial solid fraction fit well with experimental data.
Journal ArticleDOI

CFD modeling of gas flow in porous medium and catalytic coupling reaction from carbon monoxide to diethyl oxalate in fixed-bed reactors

TL;DR: Wang et al. as discussed by the authors proposed a method to use the state-key laboratory of Chemical Engineering (Tsinghua University) for chemical engineering at the University of Fujian in China.

Experimental measurement of oxygen mass transfer and bubble size distribution in an air–water multiphase Taylor–Couette vortex bioreactor

TL;DR: In this article, experimental measurements of the volumetric liquid mass transfer and bubble size distribution in a vertically oriented semi-batch gas-liquid Taylor-Couette vortex reactor with radius ratio η = ǫ/r/rǫ −075 and aspect ratio Γ −= h/(ro −− �) −40 were performed, and the results were presented for axial and azimuthal Reynolds number ranges of Rea −119 −143 and ReΘ −= 0 −35 −×104, respectively.
