Abstract

Bu çalışmanın amacı, Hesaplamali Akışkanlar Dinamiği (HAD) sistemlerinin bugünkü yeteneklerine gore, suprem kumaş hava geçirgenliği simülasyonu için yeni bir yaklaşım geliştirmektir. Örme kumaşların kalınlık boyunca geçirgenliğinin 3 boyutlu simülasyonu FLUENT® yazılım paketi kullanılarak gerçekleştirilmiş, nümerik sonuçlar deneysel veriler temelinde doğrulanmıştır. Çalışma sonunda, deneysel sonuçların nümerik HAD sonuçları ile büyük ölçüde uyumlu olduğu bulunmuştur

PREDICTION OF AIR PERMEABILITY OF KNITTED FABRICS BY MEANS OF COMPUTATIONAL FLUID DYNAMICS

Abstract

The aim of current study is to develop a novel approach for simulation of the single jersey fabrics’ air permeability based on the present abilities of Computational Fluid Dynamics (CFD) systems. 3D simulation of the through-thickness permeability of knitted fabrics was performed by using FLUENT® software package. The numerical results were verified on the basis of experimental data. At the end of study, it is found that experimental results are highly compatible with the numerical CFD results
