Post-Processing Method Using Ellipsoidal Equation for PTV Measurement Results. 2nd Report. Extension to Unsteady Flow/Mis-Matched Vector Detection/Application to Experimental Data.

Off-axis PTV for 3-D visualization of rotating columnar flows

“…Fig. 4(b) shows the same instantaneous velocity vector distribution which is converted from scattered PTV data using the Laplace equation [14]. Here the scattered PTV data are used not only in space but simultaneously in time.…”
