Predicting turbulent flow in a staggered tube bundle

摘要

This paper presents the results of calculations performed for the turbulent, incompressible flow around a staggered array of tubes for which carefully obtained experimental results are available as part of an established ERCOFTA-IAHR test case. The Rey- nolds-averaged Navier-Stokes equations are solved using a pressure-based finite volume algorithm, using collocated cell vertex store on an unstructured and adaptive mesh of tetrahedra. Turbulence closure is obtained with a truncated form of a low-Reynolds number κ-ε model developed by Yand and Shih.
