Numerical Calculation of the Transient Process of a Self‐Priming Pump During Closed‐Valve Starting and Valve Opening

open access: yesEnergy Science &Engineering, Volume 13, Issue 10, Page 5008-5029, October 2025.
ABSTRACT To investigate the characteristics of a particular self‐priming pump during its typical starting operation, this paper constructs a circulating pipeline system that includes the self‐priming pump, tank, and other components. Initially, air is set up in the upper part of the tank and the self‐priming pump, while the rest of the system is filled

Thermal–Hydraulic Performance of Nanofluids in Turbulent Separated Flow Induced by Double Forward Facing Step With Converging/Diverging Wall

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 10, Page 1343-1362, October 2025.
Compared to experimental data of thermophysical properties of NFs, semi‐empirical models cannot estimate FOM correctly. For all working fluids, applying a converging channel instead of the canonical case was inefficient. Diverging channel was always favored compared to the canonical case. For less effective NFs, both lowering the reference velocity and

Error Analysis of a Pressure‐Correction Method With Explicit Time‐Stepping

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 10, Page 1363-1378, October 2025.
We study explicit variants of this well‐established pressure‐correction scheme for solving the Navier–Stokes equations. Step 3 is replaced by an explicit time‐integration method. We give the complete error analysis for this scheme that allows for highly efficient implementations.

Intra‐Island Variation in Wind Patterns on Sub‐Antarctic Marion Island

open access: yesGeoscience Data Journal, Volume 12, Issue 4, October 2025.
Wind speed and direction measurements, over ca. 3 years, were used to inform and validate computational fluid dynamics simulations of wind across Marion Island at a high spatial resolution. The measured and simulated data show high directional variability in wind conditions in the five different geographical sectors on the island.

Strategies for Navigating Magnetic Microrobots in Neurovascular Networks: A Numerical Analysis

open access: yesSmall Science, Volume 5, Issue 10, October 2025.
Navigation of microrobots within vascular structures is key for targeted drug delivery. This work discusses strategies for navigating microrobots through a patient‐specific neurovascular network using magnetic gradients. These strategies and the equations developed for predicting the required magnetic gradients based on microrobot diameter are ...

Fabrication of Microneedles by Pulsating In Situ Dried Electrostretching for Transdermal Drug Delivery

open access: yesSmall Methods, Volume 9, Issue 10, October 1, 2025.
The pulsating in situ dried electrostretching (PIDES) technique offers a novel approach to microneedles fabrication for transdermal drug delivery utilizing electrohydrodynamic principles. PIDES is capable of fabricating biodegradable polymeric microneedles with geometric and mechanical properties suitable for skin penetration. Drug loading and in vitro
