Flow Analysis of Air around the Pipe Inlet

Our purpose is to study the effect on the air flow around the pipe inlet. We are developing the medical electronic equipments (disposal excreta processor for persons of rest care) being aimed at reduction of mental load. In order to make the medical equipments, we have to know an air flow around the equipments. We tried to solve and investigate an incompressibility Navier-Stokes equation the air flow by numerical analysis. We supposed the static boundary con- dition on the pipe inlet.
