Research interests:

Prof. Batishchev V.A. explores the processes of heat and mass transfer in the liquid layers of solid and free boundaries. These tasks are used in the field of space research. The effects of heat transfer are used for commercial purposes, such as in the preparation of drugs, biologics, in the separation of substances. Scientific work Batishcheva V.A. devoted to the study of thermo-capillary fluid flows. These problems have recently increased interest (regularly hosts international congresses and conferences). He studies the self-similar regimes of fluid flows with free boundaries, exploring new thermocapillary effects associated with the occurrence of the secondary modes by bifurcations. Batishchev V.A. established a new non-linear properties of the boundary layers near the boundaries of free (non-uniqueness, counter, self-induced pressure, etc.). He explores the new problems of thermogravitational boundary layers near the interface of liquid media. It is found that local cooling at the free surface may occur rotational flow regime heated liquid in a thin boundary layer. This effect can explain the process of such vortex structures, like a tornado. Developed methods used in the study of biomechanics short spiral waves in the aorta of humans and animals. The research results were published in journals priority Sciences, presented at international congresses and conferences.
