ME Capstone: Damper
Our team aims to create a small-scale model and test bench to evaluate the design of ventilation systems for electric arc furnaces (EAFs). Focued on redesigning both mechanical and electrical aspects of the Direct Evacuation Control (DEC) and fume hood systems.
The model and large-scale system will maintain similar Reynolds numbers so that the flow properties are comparable between the systems. The small-scale model will allow us to reliably improve the reaction time of the system to variations in gas temperature, composition, and velocity, increase capture efficiency of the off-gas, and provide a test bench for the client to test multiple types and configurations of ventilation dampers.
For this system I designed a 3D printed two louver damper which can open and close using interconnect, as well as a number of laser cut items to change the Reynold’s number in the system we are using perforated acrylic pieces with different % open.
Additionally, I designed and printed an adapter which allows 6″ PVC to interface with 6″ ducting (female & male). These adapters will allow our client to fit existing 6″ round metal duct dampers.
