Using Numerical Dissipation Rate and Viscosity to Assess Turbulence‐Related Data Accuracy – Part 1: Experimental Setup

This is the first part of a two-part paper focusing on assessment accuracy turbulence-related data from computational fluid dynamics (CFD) simulations using effective numerical dissipation rate and viscosity. Setup CFD cases replicating swirling pipe flow experiment literature, for which measured via laser Doppler anemometry (LDA) had been reported, presented. The way viscosity were obtained each mesh cell also discussed. results study are presented in second this series.
