A Turbulent heat flux two-equation [formula] closure based on the V2F turbulence model

Karcz M., Badur J.

TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk

2003

Vol. 7, No 3

375-387

The paper deals with the proposition of a two-equation turbulent heat flux closure without any damping function. The model has been based on Durbin's V2F dynamic turbulence closure and the Deng-Wu-Xi thermal turbulence model. Both models have been implemented into the FLUENT code by a User Defined Function. Results of numerical computation have been compared with experimental data for developing a thermal field in a pipe by Nagano and DNS heat transfer prediction for a two-dimensional channel flow by Kasagi.

Numerical investigation of turbulent flow and heat transfer in channel with ribs

Myllerup L., Larsen P.

Archives of Thermodynamics

2000

Vol. 21, nr 3-4

17-24

The performance of three different low-Reynolds number turbulence models has been explored for the benchmark test of fully developed (periodic) flow in aribbed plane channel. Results are presented for two values of the Reynolds number (based on mean velocity and hydraulic diameter), Re=37,200 and Re=12,600, for which experimental data are available for the flow field and heat transfer, respectively. Comparison with experimental data includes the Nusselt number distribution along ribbed surface and profiles of mean velocity.
