The objective of this CFD study was to analyze the air and steam flows inside and around a kitchen induction hood, in order to evaluate its capacity to properly capture all steam and cooking smells generated from a stove, for various flow rates.

A high-quality unstructured mesh was generated automatically by using NUMECA's HEXPRESS™ software, and NUMECA's FINE™/Open solver was used to run 3D Navier-Stokes steady calculations. Grease filters were considered thanks to the use of porous media. Steam generation and propagation through the kitchen room and inside the hood were simulated using a multi-species approach.

Post-processing included steam volute visualization, temperature distribution, pressure contours and airflow streamlines inside the hood.
