CFD Analysis and Wind Tunnel Experiment for Ventilation Ducts with Structural Elements Inside

Ventilation ducts with a high cross-sectional area are frequently built as structural that include inside transversal beams. In this way, the requested is respected, but transverse elements will have big impact on airflow, eventually additional noise and vibration amount of energy wasted across From perspective, aim study to evaluate beams ventilation ducts, analyze different alternatives for airflow improvement using computational fluid dynamics (CFD) simulation, check simulation results in wind tunnel an experimental model. The measurements highlighted high-pressure drop and, consequently, It was found downstream beam changing flow direction, turbulences vortices initiated shadow beam. According CFD analysis, system can be improved by adding deflectors area. reduced, backflow canceled, pressure losses duct reduced up 90% compared without deflector. Therefore, 90%.
