Development of Heat Input Estimation Technique for Line-Heating Processbased on Inverse Heat Conduction Analysis

摘要

The regularization method, which improves the accuracy and thernrobustness of inverse heat conduction (I.H.C.) analysis for therndistributions of heat flux and plate face temperature during spot heating,rnis formulated. Gas temperature right on the plate, TG, and local heatrntransfer coefficient, α, can be identified from these estimates. Arnguideline for adjusting the identified TG and α is drawn up. Thernvalidity of the proposed method is demonstrated by comparing thernestimated and measured plate temperatures during spot and line heatingrnexperiments. This result indicates that calculation of the platerntemperature history can be accomplished for desired plate shape,rndimensions, and torch movement history, solely from spot heatingrnexperimental results.
