| dc.description.abstract | Turbulent flow in a water-filled rectangular parallelepiped tank of an integrated solar collector is analyzed by means of a set of two and three dimensional simulations. The geometry and the working conditions of the prototype yield an aspect ratio of Γ = 6:68, Rayleigh number of Ra = 2:2 x 10 11 and a Prandtl number of Pr = 3:42. Diff erent coarse DNS simulations and LES simulations using the dynamic Smagorinsky SGS and WALE model are presented. Validity of the Oberbeck-Boussinesq approximation is questioned. Heat transfer and first and second order statistics are studied. |
