Thermohydraulic model experimental studies for codes verification of fast reactors

The aim of the experimental research was the completion of the database with new experiments to obtain detailed data on the three-dimensional structure and heat transfer of the liquid flow and creation of the new benchmark. The comprehensive experimental study of the structure free convective boundary layer and laminar-turbulent transition under high Rayleigh number at the vertical heating surface was carry out. We investigated the correlation between heat transfer and fluid dynamics qualitatively different stages of the flow also. The data on the local fields of temperature and speed, three-dimensional data on the secondary flow in the zones of the laminar-turbulent transition and the turbulent boundary layer were obtained. Also on the model liquids were carried out studies on the mixing of liquid layers having different temperatures in the regime of mixed convection. The overall structure of the flow, spatial distributions of the temperature on the wall of the channel and the channel cross section were investigated. The dates on three-dimensional structure of the temperature and velocity fields were obtained. (author)
