Unsteady Flow Behavior and Radial Force Analysis of a Side Channel Pump Under Different Blade Tip Cutting Angles Using Computational Fluid Dynamics

open access: yesEnergy Science &Engineering, EarlyView.
The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

open access: yesArtificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Improving Moist‐Electric Generator Stability and Performance by Enhancing Interfacial Activity With Crosslinked Aminated Carbon Dots

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
A high‐performance moisture‐enabled electricity generation (MEG) device with amino‐functionalized carbon dots on flexible fabric via thermal crosslinking is presented. The thermal crosslinking strategy enhances adhesion, removes inert groups, and suppresses carbon dots migration, boosting voltage (0.90 V vs. 0.56 V) and stability over 120 h.

Off-design considerations through the properties of some pressure-ratio line of radial inflow turbines [PDF]

open access: yes, 2008
Radial turbines are commonly used in applications involving operation through severe off-design conditions. The emergence of variable-geometry systems leads to the distinction between two off-design concepts: operational and geometric off-designs.

Conditional Generative Adversarial Networks for modelling fuel sprays

open access: yesEnergy and AI, 2023
In this study, the probabilistic, data driven nature of the generative adversarial neural networks (GANs) was utilized to conduct virtual spray simulations for conditions relevant to aero engine combustors.

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

ASSESSMENT OF THE CAPABILITY OF AVAILABLE METHODS OF FLOW FIELD NUMERICAL MODELLING ON THE EXAMPLE OF AIR FLOW THROUGH A CHANNEL WITH A CIRCULAR BUMP

open access: yesTASK Quarterly, 2017
This paper is an attempt at a systematic approach to the flow field analysis in the case of air flowing through a straight channel with a circular bump. The results of the authors’ own experimental measurements are compared to those obtained by means of
