Measurement of Pressure Fluctuations inside a Model Thrust Bearing Using PVDF Sensors
Thrust bearings play a vital role in propulsion systems. They rely on a thin layer of oil being trapped between rotating surfaces to produce a low friction interface. The "quality" of this bearing affects many things from noise transmission to the ultimate catastrophic failure of the bearing itself. As a result, the direct measure of the forces and vibrations within the oil filled interface wou...
متن کاملAN1326, Barometric Pressure Measurement Using Semiconductor Pressure Sensors
The most recent advances in silicon micromachining technology have given rise to a variety of low-cost pressure sensor applications and solutions. Certain applications had previously been hindered by the high-cost, large size, and overall reliability limitations of electromechanical pressure sensing devices. Furthermore, the integration of on-chip temperature compensation and calibration has al...
متن کاملA Thermal Elastohydrodynamic Lubricated Thrust Bearing Contact Model
A fully-coupled thermoelastic model for a fixed pad thrust bearing has been developed. Pressure, film thickness and three-dimensional temperature profiles were obtained by simultaneously solving the Reynolds, film thickness, energy and force balance equations using a combined finite difference and finite element method. The elastic deformation due to the pressure and the thermal distortion due ...
متن کاملexperimental study of a transonic flow over a naca0012 airfoil by measurement of pressure fluctuations
in this research, shock wave motion, shock/boundary layer interaction, and flow separation in a transonic flow over a naca0012 airfoil were investigated experimentally. thirteen kulite sensors were utilized for measurement of pressure fluctuations over the airfoil. experiments were performed for angles of attack between -4 to 4 degrees and flow mach numbers of m= 0.39 to 0.82. the kulite sensor...
متن کاملMeasurement of pressure and density inside a single sonoluminescing bubble.
The average pressure inside a sonoluminescing bubble in sulfuric acid has been determined by two independent techniques: (1) plasma diagnostics applied to Ar atom emission lines, and (2) light scattering measurements of bubble radius vs time. For dimly luminescing bubbles, both methods yield intracavity pressures approximately 1500 bar. Upon stronger acoustic driving of the bubble, the sonolumi...
