Abstract
Laminar cleanrooms are one of the most critical environments in many industries such as pharmaceutical and microelectronics; and its air quality may be vital for both human health and products quality. It is well known that the staff movement from conventional zones to ultra-clean one may lead the airborne contaminants to penetrate the laminar area. Such an effect can be hazardous for the process quality.
In this research, the effect of person movement on the contaminant distribution through clean spaces has been investigated using both moving mesh technique and a new momentum approach as well. Comparison of the results of the present model with the moving mesh data shows the model has an acceptable accuracy in prediction of the wake zone airflow and the resultant airborne contamination.
