摘要

The paper gives the basic results of experimental investigation of hydrodynamics and heat transfer in heat-absorbing devices of the ITER thermonuclear reactor, which are subjected to one-side heating. The entire array of experimental data is obtained in the following range of parameters of water flow: pressure p = 0.7-2.0MPa, mass flux G = 340-25,000kg/(m~2s), inlet water temperature T_(in)=15-60℃ The experiments are performed with turbulent swirl flows of water for twisted tapes with the flow swirl coefficient k = 0.90,0.66,0.49,0.39,0.25,0.19, and 0, as well for test sections without a tape. Given in the first part of the paper are the data on pressure drop and single-phase convective heat transfer. Appropriate calculation formulas are derived, which reliably generalize the experimental data.
