Abstract

 Laser photochromic velocimetry was successfully used to determine details of a steady two-dimensional flow field. In the plane of symmetry of a 90° curved tube at a Reynolds number of 250, the axial and radial velocity fields were measured using laser photochromic velocimetry combined with a technique involving interpolation of the photochromic data. The wall shear stress, vorticity, and pressure field were also estimated. The experimental results were compared with those from numerical simulation. The agreement was remarkably good lending validity to the interpolation method used for this flow field.
