Abstract:We construct a space-centered self-adjusting hybrid difference method for one-dimensional hyperbolic conservation laws. The method is linearly implicit and combines a newly developed minimum dispersion scheme of the first order with the recently developed second-order scheme of Lerat. The resulting method is unconditionally stable and unconditionally diagonally dominant in the linearized sense. The method has been developed for quasi-stationary problems, in which shocks play a dominant role. Numerical results … Show more
“…Both models consist of single or multiple nonlinear, coupled hyperbolic partial differential equations that have to be solved numerically. An implicit finite difference method for hyperbolic conservative-law equations as derived by Wilders (1985) is adopted for this purpose. The computational results of both models are compared to experimental data obtained in a laboratory-scale multistage fluidized bed.…”
