• Inverse heat conduction problem
• LBM

The general approach for methods of solving the Inverse Heat Conduction Problems (IHCP) is towards faster algorithms. One solution is to eliminate time-consuming iterations. The proposed method in this manuscript, as opposed to most traditional methods, is not based on trial-and-error algorithms. It uses a direct LBM solver to estimate the unknown heat flux. To do so, a new internal boundary condition is produced. Using this internal boundary condition and performing local computations of LBM will result in a direct estimation of the unknown heat flux. The results confirm a satisfactory accuracy. Also, the accuracy of the calculations is of first order, according to the number of time steps.
