ANALYSIS OF PRESSURE FLUCTUATION BEHAVIOR DURING THE RAIL GRINDING PROCESS
Jixie qiangdu, 2016 There is some grinding pressure fluctuation on the rail grinding train operation,which affects the uneven surface of grinding rail. The dynamic model of rail grinding vehicle was established which gave full consideration to the grinding mechanism’s ...

Analysis of Unsteady Pressure Fluctuation in a Semi-Open Cutting Pump
Energies, 2020 In order to understand the pressure fluctuation characteristics of a semi-open cutting pump, the three-dimensional unsteady flow fields were calculated. External and internal flow characteristics of four schemes with different relative angles between the

Numerical Investigation of Pressure Fluctuation Characteristics in a Centrifugal Pump with Variable Axial Clearance [PDF]
International Journal of Rotating Machinery, 2016 Clearance flows in the sidewall gaps of centrifugal pumps are unsteady as well as main flows in the volute casing and impeller, which may cause vibration and noise, and the corresponding pressure fluctuations are related to the axial clearance size.

The response mechanism of pressure fluctuation to the unsteady heat release in a strong rotating environment [PDF]
, 2023 The response mechanism of the pressure fluctuation to the unsteady heat release rate at the ‘unsteady’ combustion state in a strong rotating environment was investigated using a stratified vortex-tube combustor via a large eddy simulation method. Results

Fluctuating shells under pressure [PDF]
Proceedings of the National Academy of Sciences, 2012 Thermal fluctuations strongly modify the large length-scale elastic behavior of cross-linked membranes, giving rise to scale-dependent elastic moduli. Whereas thermal effects in flat membranes are well understood, many natural and artificial microstructures are modeled as thin elastic shells.
