Subsonic organic vapor flow past a circular cylinder

Numerical simulations of subsonic flows past a circular cylinder of an organic fluid (NovecTM 649) at various operating conditions are reported in the aim of complementing recent experimental investigations conducted in the CLOWT wind tunnel at Muenster University of Applied Sciences. The configuration is representative of a rotatable Pitot cylinder probe in the crossflow of an organic vapor stream. The present results, obtained by solving the steady Reynolds-Averaged Navier-Stokes equations supplemented by the one-equation model of Spalart and Allmaras, are in reasonably good agreement with the experiments. The results show that non-ideal gas effects play a minor role in the range of conditions considered in the experiments, and that discrepancies with respect to air flow at the same Mach and Reynolds number are an effect of the different isentropic exponents.     «
