Fig. 9

The computed variation in temperature and air speed within the space behind the back protected painting canvas. The arrow colour indicates the velocity at each point. Smoothed curves of vertical and horizontal air velocity at a single cross section line is shown on the graphs below. On the right is the streamline of the airflow, which can be used to approximate the possible flow paths of a single particle within the air volume
