Numerical computation of turbulent gas-particle flow in a 90 degree bend: comparison of two particle modelling approaches
A numerical study into the physical characteristics of dilute gasparticle flows over a square-sectioned 90◦ bend is reported. Two approaches, namely the Lagrangian particle tracking model and Eulerian two fluid model are employed to predict the gas-particle flows. Renormalization Group based kmodel is used as the turbulent closure for both the approaches; however, for the Eulerian model, additi...

15 صفحه اولNumerical Modelling of Turbulent Gas-Particle Flow and Its Applications
With the increase of computer power and advancement of modeling software, the study of turbulent gas-particle flow problems using computational fluid dynamics (CFD) techniques is gradually becoming attractive in the engineering field. Two basic CFD approaches are used to simulate the gas-particle flow, i.e. the Eulerian-Lagrangian model and the EulerianEulerian model. The aim of this thesis is ...
متن کاملNumerical Investigation of Turbulent Mass Transfer in a 90° Bend
This paper presents a numerical study of local mass transfer coefficients in a 90° bend using the RNG version of k–e model to include the influence of curvature on the turbulent transport. Simulations were performed for flow through a 90°, 3-D bend for Reynolds numbers of 13500, 90000, and 390000, Schmidt numbers of 2.53 and 700 and curvature ratios of 1.5, 2, and 2.5. The differences betwe...
