Media type: E-Article Title: Direct Numerical Simulation of turbulent heat transfer behind a backward‐facing step at low Prandtl number Contributor: Niemann, Martin; Fröhlich, Jochen imprint: Wiley, 2014 Published in: PAMM Language: English DOI: 10.1002/pamm.201410313 ISSN: 1617-7061 Keywords: General Medicine Origination: Footnote: Description: <jats:title>Abstract</jats:title><jats:p>The paper presents Direct Numerical Simulations of the turbulent flow of a low Prandtl number fluid over a backward‐facing step with heat transfer. The backward‐facing step flow is investigated as a generic configuration for sudden changes in cross section. Several simulations are reported: for isothermal conditions, for heat transfer with the Prandtl number of air, and for heat transfer with the Prandtl number of liquid sodium. The simulation for air is compared to results from literature. The differences induced by reduction of the Prandtl number are then assessed by comparison of the two cases.
