Item Calculation of the contact angle of a spherical surface with a bubble in flotation(ELSEVIER, 2009) Bouhenguel, M; Kouachi, S; Bouchemma, AWe have developed a method for the calculation of contact angle of spherical particle in interaction with a bubble in the process of flotation. The balance of forces acting on the instantaneous TPC perimeter in the radial direction could connect the central angle α and the contact angle θ in only one equation depending on the modified Bond number Bo, which made it possible to couple this equation with the one of the contact angle in function of the linear tension. Some theoretical results are presented.Item Global solutions to a system of strongly coupled reaction-diffusion equations(Pergamon, 1996) Kirane, Mokhtar; Kouachi, S
