The structure and evolution of thermogravitational buoyant jets in a high-viscosity fluid above a linear source of heat suddenly switched on are studied by methods of the Hilbert optics and interferometry. Such jets can be considered as a model of an upward flow in the spreading zone in geodynamic problems associated with the behavior of the Earth's mantle at large depths. Based on the interferogram structure, three-dimensional reconstruction of the temperature field in the jet is performed. The Hilbert image of the reconstructed three-dimensional temperature field is compared with the Hilbert image and interferogram of the jet. [ABSTRACT FROM AUTHOR] |
