    Sedimentation of Dispersed Particles and Evolution of Their Distribution Function
    (Taylor & Francis Inc, 2009) Kelbaliyev, G.; Memmedov, A.
    As a result of the sedimentation of dispersed particles in channels and ducts, distribution function with respect to the particle sizes changes. Particle sedimentation is affected by the gravitational forces and the diffusional migrations to channel walls. In this article, particle sedimentation in vertical and horizontal channels is investigated depending on Pe and Red numbers. Futhermore, new expressions for the calculation of sedimentation velocity depending on the diffusional migrations in turbulent flow were developed. Finally, a distribution function resulting from the particle sedimentaton was suggested. The suggested mathematical expressions were compared with the experimental results given in the literature and a very good aggrement was found.

    Solution of an inverse problem for mass transfer in a drying process in a magnetic field
    (Taylor & Francis Ltd, 2010) Memmedov, A.; Kelbaliyev, G. I.; Alisoy, G. T.
    In this study, mass transfer in deformed porous materials is investigated theoretically and analytical solutions of mass transfer equations for investigated materials are derived. In order to determine the variation of porosity degree of the material versus time and to estimate the region where the variation of effective diffusion coefficient is regular, an inverse ill-posed problem is solved by considering the experimental data concerned with the drying of the porous material. The numerical calculations of concentration profiles and experimental results concerned with the drying of the materials in a magnetic field are given.
