Solution of Packed-Bed Heat-Exchanger Models by Orthogonal Collocation Using Piecewise Cubic Hermite Functions

摘要

Orthogonal collocation using piecewise cubic Hermite functions is used to solve the elliptic partial differential equations arising from pseudo-continuum models of heat transfer in a packed bed. Problems arising from a discontinuity in the wall boundary condition and from the semi-infinite domain of the differential operator are discussed. Comparison is made between the computed solution and experimental results. (Author)
