Published in 2021 at "International Journal of Thermal Sciences"

DOI: 10.1016/j.ijthermalsci.2021.106991

Abstract: Abstract In this work, the natural convection of a viscoplastic fluid inside an enclosure filled with many obstacles is solved numerically. The enclosure is characterized by differentially heated vertical walls, while the obstacles are heat-conducting… read more here.

Published in 2021 at "Journal of Non-Newtonian Fluid Mechanics"

DOI: 10.1016/j.jnnfm.2021.104651

Abstract: Abstract This numerical study investigates the creeping flow of an elasto-viscoplastic fluid around a plate perpendicular to the flow direction. The analysis is performed with the Finite Element Method with Lagrangian Integration Points (FEMLIP). This… read more here.

Published in 2019 at "Journal of Rheology"

DOI: 10.1122/1.5087536

Abstract: A thin fluid film formed by withdrawing a vertical plate is being studied theoretically. It is the case of a viscoplastic fluid described by the Bingham model. The boundary-value problem is formulated by the lubrication… read more here.
