Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization

Energy Science &Engineering, EarlyView.
The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Probiotic Spore Inspired Oral Drug Delivery System With Multiple‐Barriers‐Crossing Ability Modulates Gut‐Brain Axis for Parkinson's Disease Therapy

Exploration, EarlyView.
Inspired by the germination of probiotic spores, we utilize the excellent characteristics of spores to break through multiple barriers of oral brain‐targeted delivery. Besides the probiotics mediated gut‐brain communication, the spore coat proteins derived nanosystems with multiple‐barriers‐crossing ability alleviate neurodegeneration.

Immersed Boundary Projection Method for Boundaries With Slip Velocities

International Journal for Numerical Methods in Fluids, EarlyView.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

International Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

High‐Order Projection‐Based Upwind Method for Simulation of Transitional Turbulent Flows

International Journal for Numerical Methods in Fluids, EarlyView.
In this study, we evaluated the implicit large‐eddy simulation capabilities of the mass‐conserving mixed stress method for transitional turbulent flows and proposed an efficient solution method for large‐scale applications. The results presented in this work show promising outcomes for incompressible aerodynamic flow problems, which can be further ...

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).
