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

Energy 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.

Lead-lag dynamics of a rotor with stick-slip nonlinearity

, 2015
An assessment of a frictional helicopter blade attachment with regard to its influence on the dynamics of the in-plane blade motion is presented. For detailed system analysis, a 3D finite element model with contact modeling has been created and validated

Adaptive Fuzzy Energy Management of Wind‐Battery Systems With Flexible Desalination Load

Energy Science &Engineering, EarlyView.
An adaptive fuzzy energy management strategy is proposed for a wind‐battery‐powered reverse osmosis desalination system. The controller dynamically adjusts the desalination load based on wind power availability and the battery state of charge to reduce battery stress.

A Simplified Two‐Vector Approach for Common‐Mode Voltage Reduction in Model Predictive Control Drives of Permanent Magnet Synchronous Motor

Energy Science &Engineering, EarlyView.
In this study, a modified model predictive control scheme is proposed, in which a dedicated weighting factor is incorporated into the cost function to explicitly account for common‐mode voltage (CMV) effects during the control process. This modification leads to a significant reduction—up to 40%—in the magnitude of the generated CMV.

Antibacterial Hydrogel Dressing With Ca2+‐Dependent Hyaluronidase Responsiveness for Accelerating Wound Healing via On‐Demand Release of AIE Photosensitizers

Exploration, EarlyView.
This study innovates a Ca2+‐responsive hydrogel dressing that releases AIE photosensitizers on‐demand. Low Ca2+ enhances bacterial hyaluronidase (HAase) activity, degrading hyaluronic acid dressing to trigger antibacterial ROS release, while high Ca2+ inhibits HAase, preventing overdosing.
