Fig. 8From: Analyzing the influence of correlation length in permeability on convective systems in heterogeneous aquifers using entropy productionChange of entropy production number \(N_{\dot{S}}\) with time of a test ensemble comprising 12 members with a horizontal correlation length of 500Â m. The average entropy production number stabilizes after around 45,000 years, whereas the majority of ensemble members do not show a strong variation after 60,000 yearsBack to article page
