Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.

In the experiment, the TiO2 nanoporous films were made dy using multiple sprinkling technique in the home-made sprinkling box instead of the doctor blade method. The multiple sprinkling technique can quickly produce the TiO2 film and easily control its thickness, i.e. transmittance. The multiple sprinkling technique made TiO2 films receive the result that the higher heating temperature and the longer heating duration, the better photoelectric conversion efficiency . The experimental data show that the sprinkling technique is better than the doctor blade and the DSSC integrated with the photoelectrode ca.
