- Deepening knowledge of aerodynamics and hydrodynamics through practical exercises
- Comparing simulation with experimentation
- Specifics of simulations involving strong flow separation
Description
Aerodynamics and hydrodynamics describe the influence of forces acting on bodies immersed in surrounding air or water. By determining the resulting forces and their causes, you gain insights for the development of your design. Through simulation, you can achieve targeted reduction of resistance by making appropriate geometric adjustments. Typical applications for simulating external flows are not only found in aircraft, ship, or automotive engineering; for the design of antennas, wind turbines, or buildings, fluid dynamic resistance is also a crucial factor to consider.
In this course, you will learn about the forces exerted by external flows. Through practical examples of simulating external flows in air and water, you will deepen your knowledge of aerodynamics and hydrodynamics. You will receive best-practice tips, regarding the precise determination of the boundary layer, model settings, and the evaluation of your simulation results. Additionally, you will receive practical advice for simulations involving strong flow separation. Building on your initial experiences with Ansys Fluent, we will further explore the basic functionalities in this training as a foundation for a solid introduction to aerodynamic and hydrodynamic simulations.
