Direct Numerical Simulations of turbulent mixed convection in enclosures with heated obstacles

摘要

Investigation of turbulent mixed convection flows past heated obstacles has physical as well as engineering objectives, since such problems as climate con-trol in buildings, cars or aircrafts, where the temperature must be regulated to maintain comfortable and healthy conditions, can be formulated as mixed convection problems. In this type of convection the flows are determined both by the buoyancy force like in natural convection and by inertia forces like in forced convection, while neither of these forces dominates.
