Abstract
A flow display method enabling the state of flows in a plane to be grasped together with inflow into and outflow from that plane. A Doppler method, for example, is used to obtain a velocity profile at each point in a planar area (,) of interest defined in a three-dimensional flow. A flow rate profile in the planar area (,) is found on the basis of the thus obtained velocity profile. From the flow rate profile and the velocity profile there are determined source points (,) representative of inflow into the planar area (,) and sink points (,) representative of outflow therefrom. Contour lines in the flow rate profile then join the source points (,) and the sink points (,) to obtain a display of planar streamlines (,).
