Air permeability of thermally modified hemlock wood

open access: yesLes, 2022
Western hemlock (Tsuga heterophylla) is a prevalent coastal species in British Columbia (BC). Its wood has a high potential for thermal modification, a process that can affect numerous physical properties, including air permeability.

Development of tricot warp knitted fabrics with moisture management for casual shirt

open access: yesFashion and Textiles, 2022
Warp knitted mesh fabric was usually applied to sportswear due to good air transmission, but without multilayer structure and one-way transport property. In order to solve this problem, the miss-lapping structure was applied to examine the possibility to

Analytical magnetic field analysis of Halhach magnetized permanent-magnet machines [PDF]

open access: yes, 2004
We develop analytical models for predicting the magnetic field distribution in Halbach magnetized machines. They are formulated in polar coordinates and account for the relative recoil permeability of the magnets. They are applicable to both internal and

Experimental evaluation of anti-stripping additives on porous asphalt mixtures [PDF]

open access: yes, 2015
The open structure of porous asphalt mix influences its strength and durability against air, water and clogging materials. These factors cause loss of adhesion between binder-aggregate interface and loss of cohesion within the binder film.

A new model for predicting relative nonwetting phase permeability from soil water retention curves [PDF]

open access: yes, 2011
Relative permeability of the nonwetting phase in a multiphase flow in porous media is a function of phase saturation. Specific expressions of this function are commonly determined by combining soil water retention curves with relative nonwetting phase ...

Air Permeability and Microstructure of a compacted silt treated with different binder dosages [PDF]

open access: yesE3S Web of Conferences
Treating silt with hydraulic binders induces significant changes in soil microstructure, leading to changes in air permeability. The microstructure changes can be investigated using Mercury Intrusion Porosimeter (MIP), and the air permeability can be ...

Air permeability of polyester nonwoven fabrics

open access: yesAUTEX Research Journal, 2015
Air permeability is one of the most important properties of non-woven fabrics in many applications. This paper aims to investigate the effects of thickness, porosity and density on the air permeability of needle-punched non-woven fabrics and compare the ...
