Effects of Window Position and Exhaust Flow Rate on Residential Kitchen Hood Performance: A Validated Numerical Approach

Figure 7

Distribution of the CO₂ concentration and the airflow velocity in the plane of the window center and the plane of the chamber center under the flow rate of (a) 6.72 m³/min and (b) 12.16 m³/min. The airflow velocity is presented using vectors, whereas the color contour describes the distribution of CO₂ concentration.
