Abstract
In this article, the effect of duct width on fully developed turbulent airflow characteristics in a corrugated duct is investigated numerically. The k-ε model is adopted for turbulent closure, and the governing equations in three dimensions are solved using a finite volume technique. The calculations were performed with the width aspect ratio (interwall spacing/channel width) ranging from 0.1 to 1.0, with the Reynolds numbers ranging from about 2000 to 15000, and corrugation angles of 30° and 45°. An experimental study was also performed for pressure drop, velocity, and flow visualization. The detailed predictions are compared with the experimental measurements, and a good agreement between the two is obtained.
