垂直内挡板 流态化 流体动力学
2009/3/13
The effect of vertical internal baffles on the particle mixing and grain drying characteristics in a batch fluidized bed column is investigated. Experimental work was carried out in a 3 m high rectang...
An experimental study of vertical gas conveying of Geldart-D powder as a dilute phase is performed ina pipe of length 22 m and internal diameter 0.05 m using a fluidized blow tank at gas velocity rang...
从Marangoni对流胞元到大尺度界面变形的动力学不稳定性
interfacial reaction in situ produced surfactant Marangoni convection
2009/3/13
The interplay between chemistry and interfacial-tension-driven hydrodynamic instabilities has been studied experimentally. The system on hand consists of two immiscible liquids separated along an init...
In this paper, shorter residence time (a few minutes) with high yield in the trickle bed process for peracetic acid synthesis by acetaldehyde liquid phase oxidation can be realized on the selected p...
The influence of the third component on gas-liquid mass transfer was studied by use of laser holographic interferometry. Four surfactants were added respectively and experimental results show that the...
An investigation of the characteristics of flowrate transients within slug flow was conducted in a largescale outdoor testing facility. The test section consisted of a 378 m long, 7.62 cm diameter s...
The experiments of one-stage semi-circular and two-stage semi-circular impinging stream drying as wellas the vertical and semi-circular combined impinging stream drying were carried out. The velocit...
The characteristics of the dual bluff body vortex shedding is investigated, and the possibility to use dual bluff body combinations to strengthen the hydrodynamic vibration around the bluff body objec...
Experimental data on the pressure drop across different types of elbow for non-Newtonian pseudoplastic liquid flow in laminar condition have been presented. A generalized correlation has been develo...
Effect of fluid elasticity and shear-thinning viscosity on the chaotic mixing between two alternately rotating cylinders has been studied. The h-p finite element method is used to obtain high accura...
This paper presents an experimental investigation of the turbulent reacting flow in a swirl combustor with staged air injection. The air injected into the combustor is composed of the primary swirling...
An experimental study on the axial dispersion of liquid was carried out in a 0.382-m-ID flotation columnpacked with different structured packings or free of packings. The correlations of axial Pecle...

second-order moment model two-phase turbulence bubble-liquid flow
2009/3/11
A full second-order moment (FSM) model and an algebraic stress (ASM) two-phase turbulence modelare proposed and applied to predict turbulent bubble-liquid flows in a 2D rectangular bubble column. Pr...
To date, many models have been developed to calculate the flow field in the structured packing by the computational fluid dynamics (CFD) technique, but little experimental work has been carried out to...
