Convective heat transfer enhancement when using gas-solid particle two phase coolant for the Tokamak type reactor first wall cooling
Comparatively low coefficients of heat transfer to gas coolant, the necessity to remove considerable heat fluxes at sufficiently low maximum temperatures for the ITER blanket first wall demands high (above 10 MPa) pressures of helium coolant used for the purpose of a/m. This can be the reason for th...

| description | Comparatively low coefficients of heat transfer to gas coolant, the necessity to remove considerable heat fluxes at sufficiently low maximum temperatures for the ITER blanket first wall demands high (above 10 MPa) pressures of helium coolant used for the purpose of a/m. This can be the reason for the considerable decreasing of ITER reliability and safety. One of the promising ways of solving the problem in question is to use two phase gas-solid particles flow as a coolant. Experimental data from the investigation of convective heat transfer in two phase gas-solid particles systems are given. Results of calculation analysis of the ITER first wall cooling by two phase gas-solid particles flow are discussed in this paper. |
