Engineering Applications of Fluid Mechanics, led by Ran, is a new group within the Fluid and Complex Systems Research Center in Coventry University. We combine experiments, theory and numerical simulations to gain fundamental, quantitative understanding of various complex systems in which fluid flow is key. Our research interests include mass and heat transfer, multiphase and reactive flow in porous media, turbulence, aerodynamics, magnetohydrodynamics, combustion, and biomechanics. We aim to advance scientific understanding and engineering practice of a wide range of industrial and natural processes across scales, from microfabrication and CFD simulations, 3-D printing, microfluidics and filters, to water resources, geohazards, enhanced hydrocarbon recovery, carbon geosequestration and renewable energy systems.

Recent News

June 2019: A comprehensive comparison of pore-scale models for multiphase flow in porous media, led by Ruben Juanes, was published in PNAS. Our own model was able to reproduce the complex patterns across the wide range of flow speeds (Ca values) and wettability conditions, besides at strong imbibition where film and corner flow dominates.

June 2019: Oshri Borgman's paper showing how increasing spatial correlation in pore sizes leads to more preferential displacement, using numerical simulations together with microfluidic experiments (performed in the laboratory of Lucas Goehring in NTU) was published in Adv. Water Resour.

December 2018: Yonatan Ganot's study on modeling the spreading of reverse-osmosis desalinated seawater in an aquifer using stable water isotopes, was published in Hydrol. Earth Syst. Sci.. The study, led by Dani Kurtzman from the Agricultural Research Center (ARO) in Israel, offers a useful methodology for predicting the distribution of reverse-osmosis desalinated seawater in various downstream groundwater systems.

December 2018: Soumyajyoti Biswas paper on how the dynamics of a drying front propagating through a porous medium are affected by small-scale correlations in material properties, was published in Phys. Rev. Fluids. The study combined drying experiments in microfluidic cells (led by Lucas Goehring), numerical simulations (led by Ran Holtzman) and a model of invasion percolation with trapping (by Soumyajyoti Biswas).

July 2018: Roi Roded's paper in Earth Planet. Sci. Lett. presents a novel pore-scale model that captures coupling of dissolution and weakening-induced compaction. We show that the application of stress suppresses permeability enhancement, by reducing transport heterogeneity, promoting wormhole competition at high Da. Our model demonstrates that the underlying mechanism is a bottleneck effect caused by stress concentration at the undissolved stiffer downstream.
