Numerical optimization of the capture efficiency of domestic range hoods

Cooking activities are the main source of indoor pollutant emissions. Domestic range hoods are the most efficient technology to ensure a good indoor air quality. Running low efficient hoods at high air flowrates during and after cooking may ensure low concentrations of indoor pollutants in the kitchen, while being high energy demanding and noisy and leading to depressurize airtight. It is then of prime importance to develop numerical and experimental methodologies to first evaluate the capture efficiency of existing hoods and then to define new scenarios for future labelling purpose. A better insight into the flow dynamics and pollutant concentration is deemed necessary to achieve those objectives. This project aims mainly at developing a new optimization tool to propose the optimal range hood and fan configuration in terms of capture efficiency and to test experimentally this new design according to the existing standards.
