Abstract :
An implicit flux-corrected transport (FCT) algorithm has been
developed for a class of chemotaxis models. The coefficients of the
Galerkin finite element discretization has been adjusted in such a
way as to guarantee mass conservation and keep the cell density
nonnegative. The numerical behaviour of the proposed high-resolution
scheme is tested on the blow-up problem for a minimal chemotaxis
model with singularities. It has also been shown that the results
for an Escherichia coli chemotaxis model are in good
agreement with the experimental data reported in the literature.
