Finite element analysis of natural heat transfer from an isothermal array of cylinders in presence of vertical oscillations

摘要

A numerical simulation is performed to study the effects of vertical vibrations on natural convection heat transfer in an array of isothermal circular cylinders. Governing equations consist of continuity, momentum and energy equations were solved numerically by finite element method and Arbitrary Lagrangian-Eulerian kinematics description. The results showed that vertical oscillations of cylinders do not necessarily results in increment of average Nusselt number of each cylinder.
