A study of an inverse method for the estimation of impulsive heat flux

The adaptive input estimation approach which is based on the Kalman filter technique combined with a variable forgetting factor as a weighting functio n in recursive least-squares algorithm is adopted to investigate the estima tion of impulsive heat flux of inverse heat conduction problem from experim ental data. Four specific charge designs for igniters with impulsive heat f lux input are solved to illustrate the effectiveness and good accuracy of t he presented method. (C) 2000 The Franklin Institute.
