Instability of Poiseuille flow in a fluid overlying a glass bead packed porous layer
, 2009 The instability of Poiseuille flow in a fluid overlying a glass bead packed porous layer saturated with the same fluid is studied. A three layer configuration is adopted, where a variable effective viscosity is modelled between the outer fluid and porous

Mesoscale Simulations of Blood Coagulation in Flow and Quiescent Domains Using SDPD
International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 9, September 2026.Mesoscale simulations show how flow conditions and domain type (flow vs. quiescent) influence thrombin and fibrin dynamics. Changes in Reynolds and Péclet numbers, together with fibrinogen levels, affect both spatial patterns and temporal evolution, highlighting the importance of transport–reaction coupling beyond well‐mixed conditions.

The importance of mean free path in determining gas micro flow behaviour [PDF]
, 2011 We investigate whether a power-law form of probability distribution function better describes the free paths of dilute gas molecules in a confined system.

Numerical Aspects of Turbulent Blood Flow in Aorta: A Systematic Review
Engineering Reports, Volume 8, Issue 9, September 2026.The aim of this systematic review is to systematize the methodological approaches used in the state‐of‐the‐art literature, including the choice of turbulence models, validation methods, as well as the identification of the main hemodynamic parameters characterizing turbulent flow.

Subcritical Bifurcation Of Plane Poiseuille Flow
, 1973 We apply the perturbation theory which was recently developed and justified by Joseph & Sattinger (1972) to determine the form of the time-periodic solutions which bifurcate from plane Poiseuille flow.

Developing continuum‐scale models for water flow in frozen soil
Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.Abstract A widely accepted continuum‐scale model capable of accounting for pore‐scale processes reasonably remains elusive in the study of water flow through frozen soil, particularly within geo‐environmental science and geotechnical engineering applications.

A review of preferential flow and transport through root channels
Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.Abstract Preferential flow can contribute up to 80%–90% of the flow and transport in the vadose zone. The root channels are the most prevalent form of preferential pathways. They create an evolving network of preferential pathways and are biogeochemical hotspots due to preferential transport of nutrients and other organics, colonization of bacteria ...

Persistent‐Homology‐Based Descriptors of Pore Heterogeneity for Generalized Permeability Prediction
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Characterizing pore‐structure heterogeneity is essential for understanding and predicting fluid transport processes in geological formations. However, it remains challenging because conventional descriptors capture only partial structural information, making it difficult to consistently distinguish complex pore structures across lithologies ...

International Journal of Urology, Volume 33, Issue 9, September 2026.ABSTRACT Objectives Outcomes after prostatic urethral lift (PUL) may vary depending on implant position and bladder neck remodeling strategy. We evaluated the impact of bladder‐neck‐focused implant density using a four‐bladder neck implant technique on early postoperative urinary outcomes.
