This experimental study aims at investigating temperature distribution of condensation jets in the free shear layer using wavelets multiresolution. Cold dry air is discharged from a round nozzle of 10 mm in diameter into the high humidity environment. For temperature measurement, the fine thermo couple is used. It is observed from the visualization photograph using laser light sheet method that condensed particles exist around the free shear layer. From the measurement the particle increase and spreads toward surroundings as the humidity rises. The dominant temperature boundary and the mean component outside boundary were provided from wavelet separation images. These boundaries were compared with the temperature distribution provided from the experimental result.
