Temperature boundary analysis of condensation jets using discrete wavelets multiresolution and 2 dimensional image Conference Paper uri icon

abstract

  • This paper describes the application of discrete wavelet transform to the analysis of condensation jets in order to clarify the fluid and heat transfer phenomenon. The condensation jets in nozzle vicinity are experimentally visualized with laser light sheet method to obtain the condensation particle density images of the jets. The image of the condensation particle density in the jet is decomposed to the mean value and the fluctuation value images by means of wavelet multiresolution. The dominant temperature boundary and the mean component outside boundary were provided from wavelet separation images. These boundaries were compared with the temperature distributions provided from experimental results.
