Centrifugal Compressor Instability and the Reverse Propagation Mechanism in Diffusers [PDF]
At low flow rates, centrifugal compressors often experience aerodynamic instabilities, posing a crucial concern for gas turbine engineers. This study focused on a standard centrifugal compressor and investigated its aerodynamic behavior through numerical

Transitional separation bubbles and unsteady aspects of aerofoil stall [PDF]
A time-accurate solution method for the coupled potential flow and integral boundary-layer equations is used to study aerofoils near stall, where laboratory experiments have shown high-amplitude low-frequency oscillations.

This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Physical analysis of the coherent motion during hysteretic static stall of Naca foil using proper orthogonal decomposition [PDF]
At static stall of airfoil, an hysteretic behavior (corresponding to an abrupt loss of lift) has been observed leading to a partially detached flow (called state I, upper increasing angle branch) and massively separated flow (called state II, lower ...

Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Numerical investigation of recess casing treatments in axial flow fans [PDF]
T he casing treatment technique for the axial fan has never been more significant since its potential applications were recognized in gas turbines, tunnel ventilation and many other industrial applications where the axial fan would benefit from the ...

Root‐Stimulated Movements in Mimosa Pudica for Biohybrid Robotic Systems
This study demonstrates that thermal and electrical stimulation of Mimosa pudica root induces movement of the petiole and pinnules without direct stimulation of the aerial organs, thereby enabling a plant‐based robotic gripper and providing a foundation for the development of intelligent and sustainable systems.

Accurate RANS Simulation of Wind Turbine Stall by Turbulence Coefficient Calibration
Stall, a complex phenomenon related to flow separation, is difficult to be predicted accurately. The motivation of the present study is to propose an approach to improve the simulation accuracy of Reynolds Averaged Navier–Stokes equations (RANS ...

Effects of metritis on stall use and social behavior at the lying stall [PDF]
Metritis in dairy cows has been associated with changes in behavior at the feed bunk, but little is known about the effects on behavior at the lying stall. The aim of this study was to investigate stall use by primiparous dairy cows diagnosed with metritis, specifically time spent in the stall, social interactions at the stall, and lying-related ...
