The determination of turbulence intensity and air velocity distribution in the ventilated spaces are very important from the point of view of draught comfort. In most cases, in slot ventilated spaces tangential air distribution system is applied. There ar... see more

Large eddy simulation of turbulent channel flow is carried out at Ret values of 150 and 395. Mesh refinement effects are evaluated on conventional meshes, then local mesh refinement in streamwise direction is applied and investigated. The goal of the pape... see more

Based on the principle of hydrostatic bearing, in this study, several novel kinds of pistons were designed out, and the mathematic model of hydrostatic bearing on piston was established and analyzed. It was also found that, the diameter of damping hole an... see more

This paper is the first half of a two-part publication. In these papers the well-known low Mach number edge tone configuration is investigated that is one of thecanonical self-sustained flow configurations leading to simple aeroacoustic flow phe-nomena. T... see more
This paper is the second half of a two-part publication. The first part containsa detailed overview of the edge tone literature and also describes the qualitativebehaviour of the edge tone when varying its mean parameters i.e. the mean exitvelocity of the... see more
