Relationship Between Temperature Distribution and 2D Image of Condensation Jets Using Discrete Wavelets Multiresolution Conference Paper uri icon

abstract

  • This paper describes the application of discrete wavelet transforms to the analysis of condensation jets in order to clarify the associated fluid and heat transfer phenomena. An experimentally obtained, two-dimensional image of the condensation particle density around the jet was decomposed into 7 levels of resolution with their respective wavelengths. Based on the known physical characteristics of turbulent flow around the jet, levels 0 and 1 were shown to represent the steady components of the condensation particle density and the higher levels represent the fluctuating components. From the analysis images, the width of the condensation zone was obtained and this compared well with the width inferred from temperature measurements. Thus, the method was verified and also provided data not available experimentally.
