Fluid thermal conductivity of air
WebIn order to master heat transfer characteristics in the furnace and accurately control the processes, a three-dimensional mathematical model of coupling the magnetic–fluid–thermal multifield has been established in a six-electrode EFMF. The model also considers the thermal decomposition of magnesium carbonate in the furnace.
