Visualisation and quantification of the air flow pattern in ventilated spaces by using image analysis.

Author(s) : PEE M. van, BERCKMANS D., MOOR M. de, WEYER K. van de

Summary

To obtain a good air distribution around the products, it is necessary to control air movement. One needs a practical and accurate measuring technique to study air movement quantitatively. Such a method is presented using the combination of a cheap camera and a computer program to calculate automatically the coordinates of an air stream and to visualize its dynamic behaviour. Developed in two dimensions, this technique can be adapted to calculate three-dimensional coordinates. An experiment using fruit boxes in the experimental plant demonstrates the technique and the need to control the air stream to obtain a homogeneous temperature for fruit and vegetable storage.
