At present, the majority of fluid mechanisms are multi-field coupling mechanisms, and their function is also achieved in flow field. Therefore, calculating aerodynamic characteristics mechanism a symmetric field very important. However, at strong algorithm domain has problems low accuracy computational efficiency, which make it more difficult to solve problem. This article obtains vector potent...

introduction: the term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease. but considering high intraocular pressure as the only factor responsible for glauco...

Given the sophisticated nature of the blast phenomenon in relation to structures, it is of significance to accurately investigate the structure behavior under blast loads. Due to its rapid and transient nature, blast loading is one of the most important dynamic loadings on the structures. Since masonry materials are widely used as the partition and bearing walls in the existing and newly-built ...

Introduction: Pressure ulcer is a kind of skin disorder that is developed due to increase of localized pressure on a part of body. Due to the terrible consequences of pressure ulcer, it is essential to prevent it. A common method to prevent is using risk assessment scales. The aim of this review study is to identify the best risk assessment to prevent and reduce the incidence of pressure ulcer....

Abstract: An experimental study is carried out in a cavitation tunnel on a propeller operating downstream of a non-uniform wake. The goal of this work is to establish quantitative correlations between the near pressure field and the cavitation pattern that takes place on the propeller blades. The pressure field is measured at the walls of the test section and in the near wake of the propeller, ...

In direct numerical simulations of strongly stratified turbulence we have previously studied the development of large scale magnetic structures starting from a uniform background field. This is caused by an instability resulting from a negative contribution of small-scale turbulence to the effective (mean-field) magnetic pressure, and was qualitatively reproduced in mean-field simulations (MFS)...

A particle accelerated computational fluid dynamics (CFD) boundary element method (BEM) technique is proposed that allows the total sound pressure field produced by low Mach number flow past a rigid body to be predicted. An incompressible CFD solver is used to calculate the transient hydrodynamic flow field. The CFD/BEM coupling technique is then used to compute the acoustic pressure and pressu...
