The laser interfero-holographic and tomographic analysis of concentration and temperature distribution of a three dimensional transient diesel spray

摘要

This paper provides a new measuring technique to obtain the concentration and temperature field of a unsymmetrical three dimensional transient diesel spray by the laser interfero-holographic and tomographic analysis. The theory to get the concentration and temperature distribution of a spray by laser technique is stated in detail. The experimental installation and optical system are given concretely. Finally, the test results are analyzed satisfactorily.
