The Comparison of Two Calculation Methods of Billets Heating in Furnaces with the Help of Zone and FVM Methods

Abstract

The comparison of two modelling methods for radiation heat exchange – finite volume and zonal methods – has been provided. The mathematical model of heating concast bars ring furnace has been created. Modelling of different heat modes of this furnace has been completed. In the result of modelling, it is shown that these methods demonstrate similar accuracy of obtained temperature values (not exceeding 50∘C). The calculation time of FVM method is greater than zonal method to 13%, because recalculations of absorption coefficients by EWBM method is needed.



Keywords: radiation transfer, mathematical modeling, zonal method, discrete transfer zonal method
