Abstract

Many studies have used commercial CFD software to predict and optimize the odor performance of hoods. In this study, it is aimed to simulate the test conforming to the European norm with CFD software. In accordance with this purpose; A full-scale kitchen and hood-mounted AFCV is modeled in Ansys Fluent software. The effect of hood flow rate and AFCV design, on capture efficiency and methyl ethyl ketone (MEK) extraction has been investigated 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 400m3/h flow. It is great to hear that this study has provided valuable insights for developing high-efficiency ventilation systems with improved indoor air quality and low energy consumption for ventilation systems.
