Examination of methods for obtaining heat transfer coefficients by quenching small probes

摘要

The present paper describes the examination result for the estimation methods for the heat transfer cofficients from the cooling curve data of small probes such as JIS silver probe,ISO Inconel alloy probe.A computer program "InvProbe-2D" with the combination of a lumped-heat-capacity method and a 2-dimensional inverse method was developed to estimate the heat treansfer coefficient from the cooling curve data.The rsults calculated by the InvProbe-2D were compared with the values calculated by the other inverse method and a lumped-heat-capacity method.It was confirmed that the inverse method program InvProbe-2D is most suitable to estimate the heat transfer coefficients from the cooling curve data in quenching of small probes.
