ON EFFICIENT APPROXIMATION OF THERMOPHYSICAL FIELDS IN THE HEAT TRANSFER PROBLEMS

摘要

The issues of efficient approximation of thermophysical fields in the heat transfer problems have been examined. The method of the proper orthogonal decomposition and method of the polyargumental systems for solving approximation problems have been compared. The key aspect of these methods is special determination of basis functions. Perspective use of method of the polyargumental systems for creation of low-dimensional models of the heat transfer problems has been outlined.
