Abstract: An approach to the numerical identification of the hydrodynamic and thermal initial sections in a flat horizontal channel with thermal boundary conditions of the first kind is proposed for laminar flow of the Newtonian fluid. The approach is based on a preliminary linearization of the hydrodynamic subproblem within the framework of a unidirectional flow and Oseen’s approximation with the simultaneous expression of the axial pressure through the tangential stresses on “wetted” surfaces. An explicit finite-difference scheme has been constructed that provides simultaneous consideration of the development of the hydrothermal situation of hydrodynamic and thermal fields on the same grid. The results of the computational experiment correlate rather well with classical data.
