Pressure Recovery of Rotating Diffuser With Distorted Inflows
Journal of Fluids Engineering, 1987The pressure recovery and velocity distributions in a two-dimensional rotating curved diffuser have been studied experimentally when even and uneven flows, respectively, were introduced to the diffuser. Two types of uneven flow were adopted; one has a linear velocity gradient on the surface of revolution and the other a linear velocity gradient in the ...

Pressure-induced optical distortion in laser windows
Journal of Applied Physics, 1973Theoretical studies are made of the effects of pressure on candidate materials for use as windows in high-power infrared laser systems. When the window in a laser system is subjected to a uniform static pressure, the resulting deformation can distort the laser beam or fracture the window.

Scale distortion from pressure baselines as a source of inaccuracy in triple-isotope measurements.
Rapid Communications in Mass Spectrometry, 2018RATIONALE Isotope ratio measurements have become extremely precise in recent years, with many approaching parts-per-million (ppm) levels of precision.

A finite element method to evaluate the pressure distortion coefficient in pressure balances
High Temperatures-High Pressures, 1999The increasing interest in high-pressure primary standards has led in recent years to special attention to the design and metrological characterisation of pressure balances, in particular to the evaluation of the pressure distortion coefficient of piston - cylinder units.

Effect of pressure on the lattice distortion of indium to 56 GPa
Physical Review B, 1991The change in the axial radio c/a of indium has been precisely determined under pressures up to 56 GPa at room temperature. The high-pressure powder-x-ray-diffraction techniques utilize an imaging plate and a synchrotron-radiation source. The axial ratio of the face-centered tetragonal lattice increases with pressure from the value at atmospheric ...

Correcting Distortions in Measurements of Atmospheric Pressure Fluctuations
Boundary-Layer Meteorology, 2008Although recognized as important, measurements of turbulent atmospheric pressure are considered difficult and are conducted infrequently. Here we discuss the essential elements in the design of an instrument for measuring turbulent fluctuations of atmospheric pressure.
