Effect of difron-4201 depressor additive on paraffin deposition in different modes
Egyptian Journal of PetroleumThis study investigates the effect of the Difron-4201 depressor additive on asphaltene–tar–paraffin sediments (ATPS) deposition in high-paraffin oil under laminar and turbulent flow regimes. At this time, the oil product of well No.

Direct numerical simulation of 'short' laminar separation bubbles with turbulent reattachment [PDF]
, 2000 Direct numerical simulation of the incompressible Navier–Stokes equations is used to study flows where laminar boundary-layer separation is followed by turbulent reattachment forming a closed region known as a laminar separation bubble.

Advanced Healthcare Materials, EarlyView.A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the

Laminar–turbulent coexistence in annular Couette flow
, 2019 International audienceAnnular Couette flow is the flow between two coaxial cylinders driven by the sliding motion of the inner cylinder. It is investigated using direct numerical simulation in long domains, with an emphasis on the laminar-turbulent ...

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
