Determination of heat transfer coefficients during solidification of a casting in a jet crystallizer

The problem of determining heat transfer coefficients in thermal processes described by nonlinear initial boundary-value problems for heat conduction equations in a cylindrical coordinate system is considered subject to axial symmetry. An algorithm is suggested and program means are created for identifying heat transfer coefficients. A computational experiment on determining heat transfer coefficients for the AK12 alloy is carried out, and recommendations for selecting numerical calculation parameters have been developed.
