Dynamic simulation of a peristaltic micropump considering coupled fluid flow and structural motion [PDF]

, 2007
This paper presents lumped-parameter simulation of dynamic characteristics of peristaltic micropumps. The pump consists of three pumping cells connected in series, each of which is equipped with a compliant diaphragm that is electrostatically actuated in

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.

Gear Pump Versus Variable Axial Piston Pump in Electro-Hydrostatic Servoactuators

Actuators
This paper presents a comparison of some different configurations of electro-hydrostatic actuators (EHA). The gear pump EHA has a simpler mechanical configuration, but the electronic power command circuits and the electric motor are in high demand due to

Mechanoluminescence of a Ba4Si6O16:Eu2+, Ho3+‐Containing Glass‐Ceramic: Experiments Under Different Loading Modes and Modeling

physica status solidi (a), Volume 223, Issue 10, 22 May 2026.
A glass‐ceramic from the BaO‐SiO2 chemical system emits light under mechanical loading provided it was submitted to UV irradiation prior to mechanical loading. This phenomenon is known as elasto‐mechanoluminescnence and, in the present case, it occurs thanks to the incorporation of a few percents of europium and holmium and an original synthesis route ...

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...

Modeling, Validation, and Control of the IEA‐15 MW Reference Wind Turbine and VolturnUS‐S Platform

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT This paper presents the acausal modeling, validation, and control of floating offshore wind turbines (FOWTs). The model simulates the IEA‐15 MW reference turbine and the semi‐submersible VolturnUS‐S platform utilizing a Control‐oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS), which integrates the key coupled aero ...
