CFD modeling of contaminant capture with an air flow control valve in a full-scale kitchen: An experimental and numerical study.

Several studies have utilized commercial Computational Fluid Dynamics (CFD) software to predict and optimize hood performance in reducing odors. In this study, our objective is to simulate the European standard test using CFD software. To achieve this objective, we modeled a full-scale kitchen and hood-mounted Air Flow Control Valve (AFCV) using Ansys Fluent software. We investigated the impact of hood flow rate and AFCV design on capture efficiency and Methyl Ethyl Ketone (MEK) extraction in detail. The analyzes simulate the capture of the heated water vapor and MEK mixture by the AFCV. The analyzes have been validated with experimental results for different flow rate conditions and have been used with confidence to model the MEK diffusion in a realistic kitchen. Thanks to the innovative AFCV created, an 8% improvement has been achieved in capture performance at a flow rate of 100 m3/h. The experiments have been repeated at different flow rates, when evaluated in terms of system pressure required for flow rate and energy consumption, approximately 27% savings were achieved at 400 m3/h flow. It is great to hear that this study has provided valuable insights for developing high-efficiency ventilation systems (hood) with improved indoor air quality and low energy consumption for central ventilation systems.
