Solving the Axisymmetric Inverse Heat Conduction Problem by a Wavelet Dual Least Squares Method

We consider an axisymmetric inverse heat conduction problem of determining the surface temperature from a fixed location inside a cylinder.This problem is ill-posed; the solution (if it exists) does not depend Fitted Hats continuously on the data.A special project method—dual least squares method generated by the family of Shannon wavelet is Conditioner applied to formulate regularized solution.Meanwhile, an order optimal error estimate between the approximate solution and exact solution is proved.
