On different modifications of the capillary model of penetration of inert liquid metals into porous refractories and their connection to the pore size distribution of the refractories

Abstract: Different modifications to the classical capillary model of penetration of liquid metals into porous refractories are presented; (1) with capillaries having different radii, (2) with zigzag capillaries, and (3) with capillaries, having periodically changing capillary radius along the path of penetration. All the modified capillary models were checked against our experimental results of measuring the penetration of liquid mercury into three types of alumina refractories, having different microstructure and pore… Show more

“…Now let us apply Equation (10a) for the case of a ¼ s, b ¼ l, c ¼ v, that is, for the solid particle at a liquid=vapor interface, by taking into account the Young equation: Equation (10b) was used to derive equations for penetration=infiltration of liquids into porous solids of different morphologies: solids with capillaries of different shapes, [31][32][33] solids made of closely packed equal spheres, [34,35] solids made of cylindrical fibers, [36][37][38] solids with irregular porous structure, [39][40][41][42] being the extension of the Carman equation [43,[44][45][46][47][48][49][50][51][52] ). Now, let us apply Equation (10b) to the classical problem of capillary rise.…”
