For realization of this project, large-scale studies of heat transfer and hydrodynamics of the flow in the channels, simulating conditions close to real are required. These conditions are primarily the flow of an electrically conducting fluid in a magnetic field and thermo-gravitational convection, emergering due to strong heat fluxes. Recently in our research group in MPEI-JIHT RAS, obtaining experimental data has become possible due to creation of model stands to identify patterns of MHD flow in a magnetic field under the action of heat flux. It is necessary simple algebraic models, resulting the main parameters of the flow and not requiring large computational resources. Besides that, obtaining experimental data will be used for validation and verification of computational codes. This project examines the influence of thermo-gravitational convection on the upward flow of a liquid metal in a rectangular channel (aspect ratio 1:3). This configuration matches to the Russian-Indian project of cooling the ITER blanket. Currently, the participants of the project are creating of a model including the influence of magnetic field on the flow. This work is dedicated to the creation of a model including the influence of thermo-gravitational convection without influence of magnetic field.
