A vortex damper is a flow control device used in exhaust systems, HVAC, power plants, and industrial ducts to regulate airflow by adjusting vanes inside a cylindrical or rectangular housing. In SolidWorks, it is designed using Extrude, Revolve, and Assembly features, with motion and flow simulations for performance analysis. Made from materials like stainless steel or aluminum, it optimizes gas flow, pressure, and temperature control in applications such as boilers, turbines, and kilns, improving efficiency and reducing emissions.
