Course Contents:
Students will learn various existing technologies of atomization, spray transport and wall collision. The course will include the lectures on the types of atomizers and their principles, typical spray parameters and the methods of spray characterization, mechanisms of atomization and their theoretical modeling, dynamics of motion of drops in a gas, drop collisions. Numerical methods for simulations of spray transport will also be reviewed.
The topics of the course include
- Single particle motion
- Bubble transport, bubble dynamics
- Thin liquid films
- Instabilities
- Sprays and aerosols
- Suspensions and emulsions
- Flows in porous media
- Granular media, granular flows
- Flows with phase change

Official Course Description:
Multiphase flows are involved in a variety of important industrial processes, such as spray combustion, chemical engineering, food production, cleaning, oil production and many many others. Multiphase flows are typical not only to many industrial processes, but also to various natural, biological processes, including even an expansion of the viruses.
During the course students will learn the existing state of the art of the phenomena involved in the multiphase flows and the major relevant physical mechanisms. The lectures will include also the examples of the theoretical models of the most interesting phenomena. However, also some interesting mathematical tools, novel diagnostic instruments and computational approaches will be introduced.
After the course students will be able to chose a suitable diagnostics for spray transport characterization, they will be able to chose a suitable method for numerical simulation of spray propagation, for the flow in the suspensions, bubbly flow with cavitation or in the porous media. They will be aware on the modern theoretical approaches in the field of multiphase. Moreover, this course will be very helpful for the succesfull master or doctoral studies in the framework of several SFB research centers at the Faculty of Mechanical Engineering.
