Abstract

The article considered an algorithm for carbon fiber-reinforced plastic thermal conductivity determining as a function of temperature while its chilldown in criostated chamber down to the temperature of 2.6 K. The said problem is being solved by the extremum seeking during meansquare deviation minimization between theoretical and experimental temperature fields in the places of temperature sensors placing. Iteration regularization method, where iteration number is the regularizable parameter, is applied as regularization to overcome incorrectness of the “direct” thermal exchange problem setting.

Keywords:

inverse problem of thermal conductivity, iterative regularization method, helium temperature level, cryostat
