Abstract
We have developed a blood flow meter using a curved pipe. In this study, we investigated the influence of the bending angle of a curved pipe on flow measurement by means of computational fluid dynamics (CFD) analysis. We analyzed the pressure distribution and the secondly flow in the curved pipe. As a result, the measurement positions for the blood flow were determined. Corresponding to increase of the bending angle, although the measurement accuracy was improved, the influence of the secondary flow was increased.
