Prediction of the Bank Formation in High Temperature Furnaces by a Sequential Inverse Analysis with Overlaps

摘要

This article presents a simple sequential inverse method for predicting time-varying thickness of the phase change protective bank found on the inside surface of a wall of a high temperature furnace. The main feature of the proposed overlapping procedure is its unique capability to increase the diagnostic frequency for phase change processes with large thermal inertia. The inverse method rests on the adjoint problem and the conjugate gradient method, and it relies on nonintrusive temperature measurements. Results also indicate that under typical melting furnace operating conditions, the proposed overlapping procedure doubles the allowable diagnostic frequency for predicting the time-varying bank thickness.View full textDownload full textRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10407782.2011.616777
