DIMENSIONLESS PHYSICAL-MATHEMATICAL MODELING OF TURBULENT NATURAL CONVECTION

Natural convection heat transfer is present in the most diverse applications of Thermal Engineering, such as electronic equipment, transmission lines, cooling coils, biological systems, etc. The correct physical-mathematical modeling this phenomenon crucial applied understanding its fundamentals and design thermal systems related technologies. Dimensionless analyses can be study flows to reduce geometric experimental dependence facilitate process main influence physical parameters; besides being used creating models prototypes. This work presents a methodology for dimensionless natural turbulent over isothermal plates, located an “infinite” open environment. A consolidated model was defined studied problem situation. numbers Grashof, Prandtl, Turbulent Prandtl demonstrated. use Theory Dimensional Analysis Similarity application tool numerical device building simplifying CFD simulations were discussed.
