3108 横流体力を利用した層流型流量計のCFD解析(S45-2 フルードパワー機器 II,S45 フルードパワー機器)  [in Japanese] 3108 CFD Analysis of a Laminar Flowmeter Utilizing Lateral Flow Force  [in Japanese]

A unique flow meter has been already proposed by the authors. It utilizes a lateral flow force generated on the inclined plate, which is placed in the rectangular flow channel. In the previous works, the mathematical model based on the 2 dimensional laminar viscous flow analysis was described and the design criterion was established by examining the fundamental characteristics. This paper addresses the theoretical analysis of the present flow meter using a computational fluid dynamics (CFD) approach to examine the flow behavior and the pressure distribution inside the flow meter. CFD analysis is carried out under the different dimensional configurations and boundary conditions. The flow versus torque characteristics is derived from the obtained pressure distribution results and then compared with the analytical model that is used for the design evaluation of the flow meter.
