Method for estimating parameters of coupled problem of interaction of gas flows loaded by solid particles with solids
The present paper outlines a method of processing and analysing experimental
data based on the methodology of the solution of inverse heat transfer problems. An algorithm
and the results of the computational and experimental study of heat transfer in the vicinity of
the critical point of a specimen in a high-enthalpy particles-loaded flow are presented. One of
the main difficulties here is how to determine coefficients of the mathematical model, which
provide its adequacy to real processes. Direct measurement of most characteristics of heat
transfer is usually impossible, and their theoretical estimates are often far from being true and
often contradictory. That is why, the unknown parameters of the heat-balance equation at the
external moving boundary of the specimen are determined from the inverse problem of heat
transfer, which is solved by the method of iterative regularization. The results of experimental
data processing for the interaction of particles-loaded flows with plane surfaces of the
cylindrical specimen are also presented as well as the optimal experiment design problems for
corresponded experiments
