Fluid flow in 3-dimensional porous systems shows power law scaling with Minkowski functionals
R. A. I. Haque, A. J. Mitra, T. Dutta
Integral geometry uses four geometric invariants -- the Minkowski functionals -- to characterize certain subsets of 3-dimensional space. The question was, how is the fluid flow in…

Three-dimensional modelling of polygonal ridges in salt playas
R. A. I. Haque, A. J. Mitra, T. Dutta
Salt playas with their tessellated surface of polygonal salt ridges are beautiful and intriguing, but the scientific community lacks a realistic and physically meaningful model tha…
