Inverse Estimates for Nonhomogeneous Backward Heat Problems [PDF]
Journal of Applied Mathematics, 2014 We investigate the inverse problem in the nonhomogeneous heat equation involving the recovery of the initial temperature from measurements of the final temperature. This problem is known as the backward heat problem and is severely ill-posed.

Convergency and Stability of Explicit and Implicit Schemes in the Simulation of the Heat Equation
Applied Sciences, 2021 Some strategies for solving differential equations based on the finite difference method are presented: forward time centered space (FTSC), backward time centered space (BTSC), and the Crank-Nicolson scheme (CN).

Application of Radial Basis Functions Meshless Method for Solving an Inverse Parabolic Problem [PDF]
Mathematics and Modeling in FinanceIn this paper, we propose an approximate solution to a one-dimensional inverse parabolic problem using radial basis functions (RBFs) and the Levenberg–Marquardt (LM) regularization method. This problem involves the backward heat equation.

Open 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.

Numerical Investigation of Nanofluid Flow over a Backward Facing Step
Aerospace, 2022 Nanofluid flow over a backward facing step was investigated numerically at low Reynolds number and the heat transfer was analyzed and reported. Al2O3–H2O nanofluids of different volume fractions (φ = 1–5%) were used as the material with uniform heat flux
