Abstract
The liquid flow perfused from a cannula into an aortic arch glass model was visualized by using the PIV method. The transparent glass model of a human aortic arch was fabricated based on the CT image of that of a normal adult man. One of five different cannulae actually used in surgical operation was inserted into the glass model. Glycerol aqueous solution having viscosity of 2.403×10^<-3> Pa s was circulated in the model at the flow rate of 4.0 L/min. A laser sheet was irradiated to the flow field simulating an extracorporeal circulation in aortic arch model to capture velocity vectors. Velocity distributions and streamlines in side and cross sectional planes were obtained based on velocity vectors. Based on the result obtained. the comparison of the flow in each cannula was performed.
