Experimental Detection of the New Phenomenon of Turbulent Thermal Diffusion Academic Article uri icon


  • The main goal of this communication is to review our recent experimental studies of a new phenomenon of turbulent thermal diffusion which was predicted theoretically in [1]. The essence of this phenomenon is the appearance of a nondiffusive mean flux of particles in the direction of the mean heat flux. This phenomenon causes formation of large-scale inhomogeneities in the spatial distribution of particles that accumulate in the regions of minimum mean temperature of the surrounding fluid. The mechanism of the phenomenon …
