R. Giudici et E. Tronconi, LAMINAR-FLOW AND FORCED-CONVECTION HEAT-TRANSFER IN PLATE-TYPE MONOLITH STRUCTURES BY A FINITE-ELEMENT SOLUTION, International journal of heat and mass transfer, 39(9), 1996, pp. 1963-1978
A numerical solution is obtained by the finite element method for the
Graetz problem of forced convection heat transfer in the channels of p
late-type monolith catalysts. For this purpose a generalized model is
constructed for the duct geometry, the fully developed laminar velocit
y profile is calculated. and the heat transfer problem is solved for b
oth uniform wall heat flux or temperature. The results are summarized
in interpolated functional forms providing the axial evolution of the
Nusselt number. Such formulae represent a prerequisite to the developm
ent of design equations for mass-transfer coefficients in plate-type m
onolith catalysts for the selective catalytic reduction of NOx with am
monia.
