Deformation of Droplets and Bubbles in Rheological Fluids

The authors have proposed different models of deformation of droplets and bubbles in regular and non-Newtonian fluids depending on Weber, Morton, and Reynolds numbers. Consideration has been given to a geometric interpretation of the issues of deformation with the aim of evaluating the surface and volume of a deformed droplet. The influence of asphalt and resin material contained in heavy oils on the degree of deformation of the droplets in them has been evaluated. Models of deformation of droplets and bubbles in regular and non-Newtonian fluids have been developed. It has been noted that the change in the shape of droplets in heavy oils is slight owing to their high viscosity. A comparison of the proposed models of deformation of droplets with the existing experimental data and with other models has been made.
