On the impact of spatially heterogenous permeability on free convection in the Perth Basin, Australia

J Niederau, A Ebigbo, G Marquart, J Arnold, C Clauser - Geothermics, 2017 - Elsevier
We study the impact of spatially heterogeneous permeability on the formation and shape of
hydrothermal porous flow convection in the Yarragadee Aquifer by modelling three …

Analyzing the influence of correlation length in permeability on convective systems in heterogeneous aquifers using entropy production

J Niederau, JF Wellmann, N Börsing - Geothermal Energy, 2019 - Springer
Hydrothermal convection in porous geothermal reservoir systems can be seen as a double-
edged sword. On the one hand, regions of upflow in convective systems can increase the …

[PDF][PDF] Entropy production and attractors: Measures to quantify uncertainty and complexity introduced by convection

J Niederau, N Börsing, F Wellmann… - Proceedings European …, 2016 - researchgate.net
We present two measures which help quantifying the impact of oscillating, convection cells
on model convergence, and model certainty:(i) The measure of an attractor in a phase space …

[PDF][PDF] On the Impact of Spatial Permeability Heterogeneity on the Characteristic Wavelength of Free Convection Cells in the Perth Basin, Australia

J Niederau, A Ebigbo, S Freitag… - Proceedings World …, 2015 - researchgate.net
When dealing with free convection in a geothermal reservoir, it is preferable to detect
regions of up flow, which locally increase the geothermal gradient. Free convection cells are …
