Estudio numérico de las cuñas salinas y de recirculación en el problema de Henry mediante los grupos adimensionales discriminados

Abstract

The Henry benchmark problem, that describes the fluid flow and solute transport phenomena involved in salt intrusion scenarios in coastal aquifers, is ruled by a set of coupled partial differential equations. Its mathematical characterization, from the discriminated nondimensionalization of the equation, leads to the two dimensionless groups that define the solution patterns of stream function and concentration. These differ from those of henry already accepted by scientific community along the last decades. By the network method, this problem is simulated for a large number of pairs of values of the groups, demonstrating that the lengths of the concentration and recirculation wedges, measured at the bottom of the aquifer, differ as values moves away from Henry arriving be disappear. The length of the aquifer is enlarged to avoid its influence in the steady state patterns.
