Sounding Mechanism of a Flue Organ Pipe—A Multi-Sensor Measurement Approach [PDF]

Sensors
This work presents an approach that integrates the results of measuring, analyzing, and modeling air flow phenomena driven by pressurized air in a flue organ pipe. The investigation concerns a Bourdon organ pipe. Measurements are performed in an anechoic

Pipe Organ Design Including the Passive Haptic Feedback Technology and Measurement Analysis of Key Displacement, Pressure Force and Sound Organ Pipe

Applied System Innovation
In this work, an organ pipe instrument with a mechatronic control system including the Passive Haptic Feedback technology is implemented. The test bed consists of a motorized positioning stage mounted to a brace that is attached to a bridge on a platform.

The Effects of the Downstream Contraction Ratio of Organ-Pipe Nozzle on the Pressure Oscillations of Self-Resonating Waterjets

Energies, 2018
Self-resonating waterjets (SRWJs) are being widely used in the fields of energy exploitation, due to the significantly increased penetration rate of roller bits in deep-hole drilling.

Influence of Wood and Thickness of Back Wall of Wooden Organ Pipe and Air Pressure in Windchest on Sound

Applied Sciences
In the past, organ builders used many tree species for the production of wooden organ pipes, and the thicknesses of the pipe walls were also different. From the point of view of the sound of wooden organ pipes, it appears that the type of wood, as well ...

Detection of Water Flow by Japanese Eel (Anguilla japonica): Behavioral and Pharmacological Analyses [PDF]

Animal Behavior and Cognition, 2023
Eels migrate long distances and their spatial learning ability based on extra-maze visual cues has been examined in the laboratory. Here, I examine the discriminative properties of water flow in their spatial cognition.
