Numerical investigation of the airflow in a food-processing clean room.

Author(s) : HAVET M., ROUAUD O.

Summary

The work deals with the simulation of the airflow in a clean room without production. The flow pattern inside the working area of a pilot scale clean room has been numerically studied using a CFD (computational fluid dynamics) code based on a finite volume formulation, in a three-dimensional geometry. Two configurations are described: global air change rate of of 103 h-1 (nominal regime) and of 51 h-1. These simulations confirm the experimental observations on the airflow. The particle tracking technique points out malfunctioning of the ventilation particularly near the "laminar zones" where extraction vents do not remove the expected outflow.
