ENGINEERING APPROACH TO THE DETERMINATION OF THE RADIATION FIELD OF A POLYETHYLENETEREPHTHALATE (PET) MEDIUM UNDER RADIANT HEATING

An engineering approach to the determination of the radiation fi eld of the PET medium under radiant heating is proposed. Instead of the reverse counting procedure for determining the radiation intensity in the negative direction, we make a correction that has a superposition character and can be determined through the refl ection coeffi cient at the boundary and the already determined radiation fi eld in the positive direction inverted in the coordinate direction. The structure of the given approach provides a reasonable balance between the adequacy of calculations and the computational resource consumption and permits estimating quickly the necessary machine time expenditures.
