Abstract

At present, technological advancement in textile chemistry leads to the innovative development of PVC-acrylic coated polyester fabrics with desirable properties for using in air-distribution systems. The objective of this research is to study variables relating to the air flow inside PVC-acrylic made air duct. The average percentage difference between the empirical result and the computational simulation was revealed at 3.26%. Pressure drops, flow rates, velocities and duct sizes were measured for constructing the diagrams revealing airflow pressure drop characteristics inside the PVC-acrylic coated air duct by using the Logarithm Curve Fitting method. As a result, the constructed diagrams can be utilized effectively for design optimization of air distribution systems.
