Abstract:

The aim of this work is to give a simple scheme for the conversion of mean zonal quantities to local quantities and to use them in solving the energy equation. The relations obtained below are derived under the assumption of sufficiently small dimensions and optical thickness of the zones. The local flux density of the incident radiation in this case may be regarded as equal to the mean zonal density. However, thermal inhomogeneity may be considerable even in a very small zone, for example, if the zone includes a flare or a boundary layer. Therefore, in solving the energy equation, account must be taken of nonuniformity of the density distribution of the intrinsic radiation within the limits of the zone. The boundary conditions specified are the temperature of the upper water-cooled wall (400 degree K) and zero heat flux through the surface of the refractory lining. At the channel inlet, a rectangular velocity profile is specified; at the outlet, the condition of flow homogeneity is adopted; at the other surface boundaries, the adhesion condition is applied. To close the radiating system, the boundaries at the inlet and outlet are taken to be nontransparent, diffusely reflecting all the incident radiation. The model derived may be used either for optimization of heating-unit operation or as a simulator in controlling the thermal conditions of a high-temperature unit.
