Hello everyone.
I was looking for some literature on translational dynamics of particles (irrespective of their shape) in viscous sublayer, and unfortunately did not find any useful information. It is well known that, particles move faster than the fluid in the buffer layer but, the question is do they move faster or slower than the fluid in the viscous sublayer?
I would appreciate if someone can direct me towards some published research articles (both numerical simulations and experimental).
Hi ...
Not sure but could Godfrey and Slater (Godfrey, J.C., Slater, M.J., 1994. Liquid-Liquid Extraction Equipment, John Wiley, New York.) help you? It is a collection of research papers dealing mainly with extraction but they discuss different types of interactions and systems. Also worth checking is a publication by Wesselingh and Bollen (Wesselingh, J.A., Bollen, A.M.,(1999). Single Particles, Bubbles And Drops: Their Velocities And Mass Transfer Coefficients. Trans. Inst. Chem. Eng. 77 (Part A),89-96.).
Best of luck!
I think you should first fix the size of particles and also flow Reynolds number. And simply by doing an experiment on flat plate using particle image velocimetry technique your question will be answered.
Please refer the papers in the enclosed document. Also, I agree with the observations of Prof Mohsen
