The instability of fronts in a porous medium [PDF]
Communications in Mathematical Physics, 1983 We use a random choice numerical method to analyze the instability of a front separating two fluids in a porous medium. We observe a linear instability and a catastrophic finite amplitude instability. A qualitative analogy with problems involving a transition to turbulence is pointed out.

Lattice Boltzmann Model for Gas Flow through Tight Porous Media with Multiple Mechanisms
Entropy, 2019 In the development of tight gas reservoirs, gas flow through porous media usually takes place deep underground with multiple mechanisms, including gas slippage and stress sensitivity of permeability and porosity.

Thermohaline convection in a homogeneous porous medium
Hungarian Geophysics, 2021 The theoretical examination of the combined effect of heat and mass transfer in porous media is relevant to improve understanding thermohaline natural convection in both local- and basin-scale groundwater flow systems. Numerical model calculations were carried out to investigate the interaction of the temperature- (ΔT) and salinity-driven (Δc) natural ...

Using MHD free convection to receive the generated heat by an elliptical porous media
Case Studies in Thermal Engineering, 2022 In many chemical processes, porous medium is usually used as a catalyst and mixing of reactants that may generate heat in thermal chemical processes.

Mechanics Research Communications, 1987 Recently the first author [ibid. 11, 277-279 (1984; Zbl 0548.76072)] has studied the flow through a very porous medium bounded by semi-infinite plate when the free-stream velocity is constant. The purpose of this paper is the study of the steady flow through a very porous medium bounded by a semi-infinite plate when the fluid is viscous and the free ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
