The main statements of the model are formulated from the statement of a general problem on determination of a temperature field in the material of a finite length-pipe, single-side heated by an external quasi-stationary heat flux with the high power density, q., = 10 MW/m2, and with the heat removal by a coolant from the parts of wetted pipe cross-section perimeter in the surface boiling regime, as well as under forced turbulent heat removal without phase transitions in the coolant.The obtained relationships are illustrated with the corresponding calculation for a cooper pipe, within a collector, with inserted twisted tape-heated by a pulse of critical heat flux from the directed ion beam, characteristic for the prescribed mode of operation under plasma heating by injection in T-15 tokamak.
1999) Method of adiabatic cross-section and its application for estimating the thermophysical and thermostrength parameters of high density beam dumps in the iter injection system, Plasma Devices and Operations, 8:1, 39-65, For the creation of serviceable designs of technical means for removing driven by various sources high-intensive heat fluxes with arbitrary spatial-temporal distributions, the method of adiabatic cross-section is proposed for calculating sets of long thin-walled pipes with an arbitrary cross-section cooled by the forced coolant flow and supplied with the heat exchange intensifiers.The arguments in support of the technique feasibility and conditions for its applicability to solve definite engineering tasks are given. The adiabatic cross-section technique eficiency is provided by an organic insertion of experimental correlations, representing the thennophysical heat exchange process parameters with a subsequent analysis of the serviceability and service lives of the structures under design, into a corresponding numerical model composed of a reduced sequence of solutions for thennomechanical plane problems of the mathematical physics.Specific features of the technique are seen in calculations of the thermophysical and thermostrength parameters of heat-removing elements in the beam dumps within the injection plasma heating system of the experimental fusion reactor ITER.The results of calculations are illustrated with distributions of the thennophysical and thennostrength parameters at the most-heat-stressed cross-sections in heat-removing pipes of the calorimeter flaps under the stationary injection conditions.
