Experimental Investigation on Acoustic Wave Generation due to Supersonic Hot Jet Impingement on an Inclined Flat Plate

Journal of Applied Fluid Mechanics, 2019
In the present paper, noise generation due to supersonic hot jet impingement (M=1.4 and Tt=950 K) to an inclined flat plate is experimentally investigated. In general, four types of acoustic waves are defined for jet impingement: acoustic waves generated

Prevalence of Cam Femoroacetabular Lesions in Medieval (1200‐1600 CE) and Postmedieval (1600‐1850 CE) Dutch Skeletal Collections

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the

Numerical and Experimental Investigation of the Influence of Backpressure on a Confined Impinging Jet for Small Nozzle-to-plate Spacing [PDF]

Journal of Applied Fluid Mechanics
In order to further extend understanding of the heat transfer characteristics under an enclosed area, the influence of backpressure on a single impingement jet with small nozzle-to-plate spacing (H/D) is studied.

Blade Count and Rotational Speed Sensitivity of Vertical‐Axis Turbines Under Guided Vehicle‐Generated Transient Wakes

Energy Science &Engineering, EarlyView.
Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Rarefied planar jet and jet impingement flows [PDF]

AIP Conference Proceedings, 2012
This paper presents three sets of analytical exact solutions to collisionless gas flows from a two-dimensional exit. The first set is free plume expanding into a vacuum, and the other two sets are collisionless plume impingement at a vertically set plate.
