Performance Improvement of a Closed-Conduit UV Reactor by Asymmetric Lamp Positioning using CFD

초록

The performance of a closed-conduit ultraviolet (UV) reactor was improved by changing the lamp positions from symmetric to asymmetric. This goal was achieved by incorporating the performance factor reduction equivalent dose(RED). The fluence rate modeling was performed by using UVCalc3D. The results of the four asymmetric cases were compared with the symmetric one. The asymmetric lamp presented can be useful for UV reactor design and optimization. The simulation results provide detailed information about the model configuration and RED. The RED value was increased by approximately 15% for the UVCalc3D model.
