In the Particle image velocimetry (PIV) measurement system, using the basic measurement principles of three-dimensional space position and splitting method, it, using a CCD camera, achieved the measurement to a space position. Light emitting diodes flash twice and image in the same CCD camera and space vector can be obtained directly by the image processing, and then three-dimensional velocity field can be obtained.

AbstractFor a spatially periodic convection-diffusion problem, we analyze a time stepping method based on Lie splitting of a spatially semidiscrete finite element solution on time steps of length k, using the backward Euler method for the diffusion part and a stabilized explicit forward Euler approximation on {m\geq 1} intervals of length {k/m} for the convection part. This complements earlier work on time splitting of the problem in a finite difference context.
