Design, Simulation and Testing of Linear Cascades

In this tutorial, students are introduced to the design of turbomachinery aerofoils by means of a practical example demonstrating the structural design, numerical simulation, and experimental testing. Following the introduction to the underlying aerodynamics and the basics of required software tools, the students form teams to develop their own aerofoil in a hands-on approach. The focus of this tutorial is on the methods for the design of 2D-aerofoils.

Recommended for 7th semester

GOAL

Each team designs an aerofoil using software tools. The design is based on pre-defined target parameters and boundary conditions. Numerical simulations (CFD) are performed to verify the design and improve the aerofoil iteratively. The resulting aerofoil design is implemented using CAD software to create a printable 3D model.

Each team presents their aerofoil in a design review. They defend engineering and economic aspects of their design process to in a plenary session.

Following the tutorial and depending on the design review, teams are given the opportunity to produce their aerofoil using a 3D printer to assemble a linear cascade to be tested in a wind tunnel experiment. Relevant aerodynamic performance parameters are measured and compared with preliminary CFD results.

In addition to using software for engineering design, experimental measurements, and numerical simulation, students are challenged to handle problems without a preconceived solution in a self-reliant and result-oriented manner. Students are given the opportunity to use and develop good engineering practices. Knowledge obtained from the lecture “Aerothermodynamics of Turbomachinery” can be applied to a practical example. Contents of other lectures such as “Aircraft Engines”, “Computational Fluid Dynamics”, and “Experiments and Measurements in Fluids” can be applied and consolidated. Students practice their ability to work in a team and gain an insight into engineering work.
