Vibration characteristics of axial piston pump based on phase trajectory diagram

Journal of Measurement Science and Instrumentation, 2023
Considering that the vibration of the piston pump shell includes not only motion state information, but also energy state information, this study discloses the relationship between the piston pump vibration signal and the operating state by the piston ...

Enabling Ultrastable Microbubbles With Graphene Aerogel Enrichment and Machine Learning for Highly Efficient Carbon Storage

Electron, Volume 4, Issue 3, August 2026.
This study aims to introduce a novel‐designed structure of the colloidal aphron microbubbles reinforced by incorporating hydrophobic aerographene microparticles onto the hydrophobic outer shell. This results in the formation of a robust composite film and armored microbubble that offers exceptional ultrastability under elevated pressures of up to 400 ...

Research on source impedance characteristics of an axial piston pump

Nihon Kikai Gakkai ronbunshu, 2019
The fluid borne-vibration generated from a hydraulic pump is known to be one of drawbacks in hydraulic systems. In order to decrease the noise and vibration effectively, the simulation tool to predict the pressure ripple at an arbitrary point in the ...

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Rheological Modeling and Numerical Simulation of Annular Flow of a Drilling Mud Based on Local Materials: Theoretical Parametric Study

Engineering Reports, Volume 8, Issue 8, August 2026.
Numerical and analytical modeling of annular flow reveals the hydraulic performance of sustainable drilling muds formulated from Congolese kaolinitic clay, okra mucilage, and plant ashes. Yield stress enhances cuttings transport, while shear‐thinning behavior reduces pressure losses and pumping energy.

Effect of Flow Dynamics on Two‐Phase Flow Patterns in Porous Media

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the impact of flow dynamics on liquid‐gas two‐phase flow patterns within a two‐dimensional millifluidic porous medium. Based on high‐fidelity analysis of experimental images and simplified single‐phase flow pore network models (PNM), we examine co‐injection two‐phase flow configurations across varying injection rates ...

Effect of Thickener Rheology on Bolus Cohesivity in Dysphagia Management

Journal of Texture Studies, Volume 57, Issue 4, August 2026.
Thickened liquids have different rheology: Newtonian ones lack cohesivity and cause aspiration, while elastic and shear‐thinning types form cohesive boluses preventing airway entry. Elasticity and extensional effects govern bolus integrity, so shear viscosity alone is insufficient; a “bolus cohesivity number” integrating viscous, elastic, inertial, and

Year‐round spawning increases throughput of genetic modification of common carp (Cyprinus carpio)

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The common carp (Cyprinus carpio) is an economically and ecologically significant species. It is both one of the most highly produced fish in aquaculture globally and a persistent, widespread invasive species. Research efforts focused on understanding its biology, improving traits for aquaculture, and generating next‐generation carp control ...
