Using CFD to find the best placement of HDD production machinery for major renovation of factory clean room

Abstract

HDD production needs to be done in a clean room that keeps particulate contamination to the minimum. In planning a renovation of a clean room in an HDD factory in Thailand, a question came up whether to put components of HDD production machinery on raised platforms or keep them on the floor level in order to better minimize contamination. This study was conducted to find the answer using computational fluid dynamics (CFD) simulation software, Ansys Fluent, combined with the real ventilation conditions planned for the clean zone. The simulated results showed that keeping the machinery in the same level with the floor is more effective.
