Abstract
In order to remove a bad smell around bedside, evaluation of the flow of the air around the bedside is done from a theoretical side. Simulated calculations are performed for various conditions. The calculation is based on the Navier-Stokes equation. The flow vectors are drawn for seveval models for the comparison between models. The shapes of the nozzule of the inlet are compared, and it is shown that the wide nozzule shape is more effective than the other shapes. A system is newly evaluated, which has a pair of outlet and inlet in their oposite side. It is concluded that the circulation of the flow is much effective, since the air works in both ends. These findings are a guideline which makes it possible to construct a new machine to remove effectively the odor around bedside.
