The Solution of Backward Heat Conduction Problem with Piecewise Linear Heat Transfer Coefficient [PDF]

open access: yesMathematics, 2019
In the fields of continuous casting and the roll stepped cooling, the heat transfer coefficient is piecewise linear. However, few papers discuss the solution of the backward heat conduction problem in this situation.

A quasi-boundary value regularization method for the spherically symmetric backward heat conduction problem

open access: yesOpen Mathematics, 2023
In this article, we investigate a spherically symmetric backward heat conduction problem, starting from the final temperature. This problem is severely ill posed: the solution (if it exists) does not depend continuously on the final data.

Determination temperature of a heat equation from the final value data [PDF]

open access: yesSurveys in Mathematics and its Applications, 2012
We introduce the truncation method for solving a backward heat conduction problem. For this method, we give the stability analysis with new error estimates. Meanwhile, we investigate the roles of regularization parameters in these two methods.
