Numerical prediction of fluid-resonant oscillation at low Mach number

open access: yes6th Aeroacoustics Conference and Exhibit, 2000
A method (governing equation set and numerical procedure) suited to the numerical simulation of fluid-resonant oscillation at low Mach numbers is constructed. The new equation set has been derived under the assumption that the compressibility effect is weak.

Low Mach Number Limit of the Full Navier-Stokes Equations [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2005
The low Mach number limit for classical solutions to the full Navier Stokes equations is here studied. The combined effects of large temperature variations and thermal conduction are accounted. In particular we consider general initial data. The equations leads to a singular problem, depending on a small scaling parameter, whose linearized is not ...

The Role of Obesity in the Association Between Alcohol Consumption and HDL‐c Levels: Baependi Heart Study

open access: yesLipids, EarlyView.
ABSTRACT Cardiovascular diseases (CVD) are a leading cause of global mortality, with dyslipidemia playing a central role in their pathogenesis. The influence of alcohol consumption on lipid profiles, particularly high‐density lipoprotein cholesterol (HDL‐c), in relation to obesity status remains insufficiently explored.
