Abstract
We performed direct numerical simulations (DNS) of turbulent boundary layer flows of viscoelastic fluids with variations of solution concentration and temperature in order to investigate the effects on the turbulent statistics and structures. In this study, we proposed a new constitutive equation model, c-T-FENE-P model, in which the relaxation time varies with temperature. DNS date for 6 cases of increasing and decreasing relaxation times with temperature were investigated. It was found that the dependence of the increasing and decreasing relaxation times on the drag reduction ratio was opposite to each other.
