| Abstract |
Recently, several kinds of computational airflow simulation techniques are applied to the design of cleanrooms airflow performance.??However, these computational airflow simulation systems require much labor to setup the data of cleanroom configurations, especially when the cleanroom consists of complicated flow field.??In this research work, a new type of computational airflow simulation system applicable to the complicated flow field problems with simple in-put data was introduced.?? This system adopts the patched-type composite grid system, and the field data is treated as the composition of simple fields.??This paper describes the outline of the computational airflow simulation system and some application results on the machine-layout problem in non-unidirectional airflow cleanroom.??As the result of test applications, it was found that the computational airflow simulation system has powerful performance on solving the complicated flow field problems. |
