The two‐fluid modelling of gas‐particle transport phenomenon in confined systems considering inter particle collision effects

A. Mitter, J.P. Malhotra, H.T. Jadeja

A modelling approach of gas solid flow, considering different physical phenomenon such as fluid turbulence, particle turbulence and interparticle collision effects are presented…

Mathematical simulation of surface wave created in a mold due to submerged entry nozzle

Sukanta K. Dash, Swasti Sunder Mondal, Satish K. Ajmani

Two‐dimensional numerical simulations have been performed using a finite volume method that employs unstructured grids with cell‐wise local refinement and an interface‐capturing…

Effectiveness of several turbulence models in natural convection

P.C. Walsh, W.H. Leong

Heat transfer due to natural convection inside a closed cavity must be modeled to include the effects of turbulence if the Rayleigh number is sufficiently large. This study…

Numerical analysis of vortex shedding behind a porous square cylinder

Tswen‐Chyuan Jue

Vortex shedding behind a porous square cylinder is studied by a semi‐implicit projection finite element method in this paper. Flow fields over the porous square cylinder with…

Molecular dynamics simulation of micro‐Poiseuille flow for liquid argon in nanoscale

J.L. Xu, Z.Q. Zhou, X.D. Xu

The molecular dynamics simulation of micro‐Poiseuille flow for liquid argon in nanoscale was performed in non‐dimensional unit system with the control parameters of channel size…

Numerical studies of physiological pulsatile flow through constricted tube

Wei Liao, T.S. Lee, H.T. Low

A detailed analysis on the characteristics of laminar flow over a bell‐shaped stenosis for a physiological pulsatile flow is presented in this study. In order to have a good…
