@article{Nadeem_Ahmed_Chughtai_Ullah_2020, title={CFD-BASED ESTIMATION OF COLLISION PROBABILITIES BETWEEN FINE PARTICLES AND BUBBLES HAVING INTERMEDIATE REYNOLDS NUMBER}, volume={46}, url={http://thenucleuspak.org.pk/index.php/Nucleus/article/view/940}, abstractNote={<p>Recent literature comprises numerous investigations on the determination of bubble-particle collision probabilities in<br />flotation systems based upon hydrodynamic models. This work aims to use CFD to simulate collision probabilities in<br />quiescent flotation conditions as encountered in Flotation Columns. Euler-Lagrange approach is used for the calculation<br />of collision probabilities of fine (10Î¼m to 80Î¼m) solid particles with bubbles having intermediate Reynolds number (i.e.<br />2&lt;Re&lt;500; 0.1mm&lt;db&lt;1.5mm). In this work only two bubble sizes, 1.0 mm and 1.5 mm, are simulated. The simulations<br />are performed using both unstructured and structured meshes. The values of collision probabilities are compared with<br />those produced using the hydrodynamic models of Yoon &amp; Luttrell and Weber &amp; Paddock. The results of collision<br />probabilities and their variations with bubble and particle sizes, obtained using structured mesh are in close agreement<br />with the published data.</p>}, number={3}, journal={The Nucleus}, author={Nadeem, M. and Ahmed, J. and Chughtai, I.
