A mathematical model describes the physical phenomena and provides a deeper understanding of the process. Turbulent flow is one of the important physical phenomena in an anode baking process. In the present work, isothermal turbulent flow is studied in detail with respect to two turbulence models in COMSOL Multiphysics : Prajakta Nakate, Domenico Lahaye, Cornelis Vuik, Marco Talice. The paper presents a mathematical model for the calculation of resistance to heat transmission at the cross-flow of gas. The obtained mathematical expressions show that the resistance to heat transfer at the cross-flow of gas is determined by the following influential values: the method of setting processed elements, the setting. Design of Advanced Industrial Furnaces Using Numerical Modeling Method Wei Dong Heat and Furnace Technology, Department of Materials Science and Engineering Royal Institute of Technology (KTH), S Stockholm, Sweden Abstract This doctoral thesis describes the fundamentals of mathematical modeling for the industrial. A mathematical model of the reheating process of steel slabs in industrial fuel-fired furnaces is developed. The transient temperature field inside the slabs is computed by means of the Galerkin method. Radiative heat transfer inside the furnace constitutes boundary conditions that couple the dynamic subsystems of the slabs. Constraining the heat fluxes to piecewise linear, discontinuous.
