    Deposition of dispersed particles in isotropic turbulent flow
    (Taylor & Francis Inc, 2008) Sarimeseli, Ayse; Kelbaliyev, Gudret
    Particle deposition in turbulent flow depends on diffusional migrations and gravitational forces. However, the rate of this process occurs differently in vertical and horizontal flows. Therefore, some new expressions were suggested for these two types of flow in this article. Moreover, impact of the coalescence and break-up phenomena on deposition was investigated. Suggested equations were compared with the experimental data taken from the literature and a good agreement was recorded.

    Modeling of the Size Distribution Resulting from Dissolution of Spherical Solid Particles in Turbulent Flow
    (Taylor & Francis Inc, 2012) Ekmekyapar, Ahmet; Kunkul, Asim; Yuceer, Mehmet; Kelbaliyev, Gudret
    The process of dissolution of solid particles in turbulent flow regime is of importance in many industrial applications. A new size distribution takes place due to dissolving during the motion of a solid-liquid suspended system in a stirred vessel. An analytical relationship was derived to represent the concentration profile in diffusion boundary layer between solid and liquid. An expression was obtained between mass transfer flow from spherical particle area and particle size changing with time during dissolution of solids. A mathematical model was developed for calculating particle size distribution varying with time during dissolution of spherical solid particles. The Focker-Planck equation was used to construct the distribution function varying with particle size. Model parameters were estimated by the Genetic Algorithm, the validity of the model was confirmed with experimental data.
