DOI: 10.1016/j.ijheatmasstransfer.2018.08.013

Abstract: Abstract Direct Numerical Simulations are used to solve turbulent flow and heat transfer over a variety of rough walls in a channel. The wall geometries are exactly resolved in the simulations. The aim is to… read more here.

DOI: 10.1039/d2sm00412g

Abstract: Confinement modifies the properties of a fluid. The particle density is no longer uniform but depends on the distance from the walls; parallel to the walls, layers with different particle densities form. This affects the… read more here.

DOI: 10.1080/02786826.2020.1739617

Abstract: Abstract An equation for the probability density function (PDF) for particle velocity and coordinates in a gas turbulent flow is derived. The system of equations for the first and second moments of particle velocity fluctuations… read more here.

DOI: 10.3390/min14121213

Abstract: Modeling carbonate growth in fractures and pores is important for understanding carbon sequestration in the environment or when supersaturated solutions are injected into rocks. Here, we study the simple but nontrivial problem of calcite growth… read more here.
