Abstract
Three-dimensional natural convection in porous media at a rectangular corner was computed. Three outer surfaces of a corner were cooled, and three inner smaller surfaces of a comer were heated. The average Nusselt numbers computed on the hot walls differed by more than 100% from those on the cold waits. Four different extrapolation schemes for an average Nusselt number were invented with an extrapolation to a zero grid size. The extrapolated Nusselt numbers agreed within 1% of each other. The convective flow mode was found to consist of a pair of double helical movements
