Experimental, analytical, and numerical quantification of the Marangoni effect in static refractory finger test Open
This study investigated the local corrosion of alumina and magnesia refractory in CaO–Al2O3–SiO2–MgO slag due to the Marangoni effect, which is a key factor for localized wear in different industrial processes, using experimental, analytic…

Method for inverse calculation of erosion parameters in slag-refractory systems Open
Refractory erosion due to fluid flow is caused by the shear stresses acting on the liquid/solid interface. This mechanism of continuous wear has not been extensively investigated based on appropriate physical considerations. This study pro…

Application of an improved testing device for the study of alumina dissolution in silicate slag Open
This study entailed a dissolution study of alumina fine ceramics in a CaO–Al2O3–SiO2–MgO silicate slag system with a CaO/SiO2 weight ratio of 0.65. Finger-test experiments with several corrosion steps were carried out in a contemporary con…

Method for determination of mass transfer coefficients for dissolution of dense ceramics in liquid slags Open
This paper presents a numerical method to determine the mass transfer coefficients in the dissolution of dense ceramics in liquid slags. Simulations are based on a typical rotating finger test as the experimental set-up, where a cylindrica…

Method for determination of effective binary diffusivities in dissolution of dense ceramic materials Open
A method is proposed to determine the effective binary diffusivities in a dissolution of dense ceramics in liquid slags. This is achieved by combining computational fluid dynamics with a boundary layer approach to overcome the resolution p…
