...Jonathan K. Lai; Giacomo Busco; Elia Merzari; Yassin A. Hassan A direct numerical simulation (DNS) of bare rod bundles with a low pitch-to-diameter ratio is performed with heat transfer at different Prandtl numbers. Turbulence statistics for temperature and velocity as well as the turbulent budgets...
