PP-II-7CFD-CALCULATION OF MALDISTRIBUTION OF EFFECTIVE HEATCONDUCTIVITY COEFFICIENT IN A REGULAR PACKING OFSPHERICAL PARTICLESV.P. Zakharov, A.S. NoskovBoreskov Institute of Catalysis, 5, Akad. Lavrentiev Ave., 630090, Novosibirsk, RussiaTel.: +7-383-32-69-438; fax: +7-383-330-68-78; e-mail: xap@catalysis.ruPrimary results of computational investigation of fundamental regularities of transversalheat transfer in a simple-packed beds of balls in a slab are presented. Balls are situated in thenodes of cubic or rhombic or mixed cubic-rhombic lattices and are non-zero heatconductivity. Relative heat conductivity of the ballsΛ = λ / λ was varied from 0.01 to100. Number of balls layers from one wall of a slab to another one was set as 1, 2, or 4 at aconstant slab width. Porosity of each of the packing is equal to ca 0.62.One wall of a slab was hot, and another one – cold. Gas flow direction is parallel of cubicedges or of rhomb diagonals. At such statement, flow pattern is symmetrical, but temperaturefield is anti-symmetrical. By this, total heat flux throw the input and output boundaries of thecomputational cell is idem, and total heat flux throw the arbitrary wall-parallel section of thecomputational cell is idem too.Calculations were carried out at ANSYS FLUENT 6.3.26 program package at clustersystem NCS-160 of Siberian Super-Computer Center. Four processors were used. Tasksdiscrete dimension were depended on lattices structure and were from about 2500000 to about5000000 control volumes for computational cell.Some results of modeling are adduced on a figure below.Coefficient of effective transversal heat conductivity∂ < T >( λgas+ λeff) = Q∂ywall/ Swallλ effcatgasis defined from equation:, whereQwall∂Tgas= ∫λ gasds – integral wall heat flux;∂ySwall1< T ( y)>= TdsS(y)∫ – averaged temperature profile;S ( y)y – dimensionless transversal coordinate (normal to slab walls).Integral convective heat flux is defined as Qconv( y)= ∫Vy⋅(ρCp⋅T)gasds.S ( y)284
