Title Open cabins for stone-cutting - Comparison of vertical and "oblique" airflow efficiencies
Original title Cabines ouvertes pour la taille de la pierre - Efficacité comparée du flux vertical et du flux "oblique" [in French]
Bibliographic information 3rd Quarter 2004, No.196, p.31-42. Illus. 5 ref.
Abstract A recent study of ventilated open cabin efficiency highlighted the superiority of vertical airflow over horizontal airflow in many configurations. However, the placement of these cabins can sometimes prove difficult. This constraint has led manufacturers to offer a solution in which the main airflow is not vertical, but directed obliquely. A stonecutting sector evaluation of three cabins, one vertical and two "oblique" airflow units shows that on average, vertical airflow is more efficient than "oblique" airflow in a large number of tested situations. The two "oblique" airflow cabins gave different results: in some situations, one cabin's performance characteristics approached those of vertical airflow cabins, whilst the other gave very scattered results, with lower efficiencies than those of the other two cabins in many situations. It appears "oblique" airflow is more sensitive to the stonecutters' position and machining methods than vertical airflow.
