Hi friends
I am working for Sharif University of Technology in optic flow lab. I want to do particle shadow velocimetry with bunsen burner and I have to design seeding system which provides seeds from inside of burner. My seeds are Tio2 particle powders. I want to know details of this setup and a plan for making and needs of that. I hope you can help me.
Thanks
Hello Sajjad,
Have you tried bubbling the fuel gas through titanium tetrachloride, TiCl4, before it is sent to the nozzle in the Bunsen burner? The presence of water (steam) in the combustion gas should generate titanium dioxide, TiO2.

Hello Sajjad,
A couple of cautions if you use the TiCl4 technique. The reaction products will include hydrogen chloride, HCl, gas, which can attack the mucus lining of your throat, nose, eyes, and lungs. For this reason, make sure that the Bunsen burner is inside a functioning fume hood so that you are not breathing in either the TiO2 or the HCl.
TiCl4 produces a very dense cloud of TiO2 so you might only need to pass the fuel gas over the surface of cold TiCl4.
