SIMULATION OF THERMAL IMPACT OF FLAMES COMING FROM CLASS «B» TEST FIRE ON THE ELEMENTS OF THE ADJACENT FACILITIES

Mathematical modelling of the processes of thermal impact of flames coming from fire on the elements of the adjacent facilities by gas dynamics methods was conducted. An algorithm of application was proposed for the heat exchange between the facilities during a fire by methods of gas dynamics in order to substantiate fire separations and appropriate model was developed. Using the mathematical model having been developed proper computation of the processes of thermal impact of flames coming from fire on the elements of the adjacent facilities was conducted. Comparative curves of temperature changes were plotted for the specimens under study when performing full-scale tests and those for the computation results. Check of adequacy was conducted against criteria of absolute deviations, relative deviations, root-men-square deviations and deviations by Fisher criterion.
