The three Michael Olsen vexing research issue: How immiscible droplets according to Vigil. “Although drop breakage have developed a new fluid flow apparatus of liquid suspended in another liquid (think oil has been studied for a long time, the existence for studying drop breakage that provides the and water) break apart when agitated. It is this of multiple breakage mechanisms and the means for carefully controlling the fluid flow knowledge that is important to industrial processes lack of well-controlled experiments capable of characteristics while also providing optical involving emulsification, like the homogenization producing detailed information to understand access for high-speed photography of breakup of milk and various other food products and the underlying physics of drop breakage has events and acquisition of 3D velocity fields. The emulsion polymerization, a process that creates hindered the development of mathematical and data obtained from this apparatus could provide polymers used in things such as synthetic rubber computational models that accurately predict a much deeper understanding of the physics and latex paints. breakage rates and droplet size distributions.” of drop breakage and the development of new Over several decades, many models for To address these shortcomings, Vigil is working models for prediction and control of processes droplet breakage events in turbulent flow with his chemical engineering colleague, Anson involving breakage.

The high-speed cameras shown are capable of capturing many thousands of images each second and can be used to slow down and analyze individual droplet breakage events to determine the mechanism and statistical properties of those events. 4 Although Fox, Vigil and Olsen have all previously worked to better understand the behavior of dispersed phase bubbles, their current work was catalyzed when Fox came across a paper by French physicists who used a specially-designed small box called a von Karman swirling flow apparatus to generate uniform mixing so that they could observe the breakup of clusters of solid particles. He recognized that this technique for Center for Multiphase Flow generating homogeneous isotropic turbulence (uniform mixing) could be used for droplet breakup studies. Research and Education The project is being done in collaboration with the German company Iowa State University’s Center for Multiphase Flow Research BASF, one of the largest chemical producers in the world, and through Iowa and Education (CoMFRE) brings together faculty, students and State’s Center for Multiphase Flow Research and Education (CoMFRE), which industry leaders interested in advancing real-world applications integrates the skills of ISU investigators and industrial members to deliver for multiphase flows. advances in the field to industrial applications and end-users. Industries where multiphase flows are found range The research lab space in Sweeney Hall includes a recently-constructed area from energy and power generation to agricultural and of framework, platforms and special pieces of apparatus, including lasers and pharmaceutical companies to materials and construction. high-speed photography equipment that gets to the heart of the matter. “One of the main limitations of previous studies of droplet breakage is • Nearly 30 Iowa State faculty and staff are CoMFRE the lack of control of the fluid mixing,” Vigil explains. “Stirred tanks, which members – with expertise in chemical, mechanical, civil are widely used in industry because of their simplicity, have turbulence and aerospace engineering and other disciplines. characteristics that are spatially very non-uniform, which in turn complicates • A growing list of industry partners including AbbVie, the understanding of how the fluid mixing impacts drop breakup.” In Ansys, BP, BASF and Roeslein Alternative Energy. addition, the apparatus features precise control of the size of the droplets If your company is interested in becoming a member of introduced into the flow cell before they undergo breakage. CoMFRE, contact Ted Heindel at [email protected] Regarding their method of introducing droplets into the von Karman CoMFRE web site: https://comfre.iastate.edu box. “This is another variable over which we have unprecedented control compared to previous studies,” says Vigil. High-speed photography of drop breakage events, a laser-based method called particle image velocimetry (PIV) is being employed to gather detailed information about the fluid flow around droplets undergoing breakage. According to Vigil, PIV combined with high-speed photography of individual breakage events will make it possible to rigorously evaluate the validity of existing drop breakage models and to propose improved models. “The expertise in particle image velocimetry brought to this project by Prof. Olsen, who has decades of experience using this method, is a crucial factor in the success of the project.” Work continues with a variety of parameters employed. Following further research, a paper presenting the team’s discoveries is planned.
