Praktikum Numerische Strömungsakustik

What it is about

You work on numerical procedures for simulating sound propagation in stationary and flowing media (1D/2D) based on concrete projects. In the end you will be able to apply LEE-based finite-difference methods, assess their accuracy, and evaluate the sensitivity of results to physical and numerical modeling.

What you will be able to do

• Numerical solution of the linearized Euler equations (1D and 2D)
• Assessment of dispersive and dissipative errors
• Analysis of factors such as grid anisotropy, wave direction, and truncation order
• Application of absorbing boundary conditions and buffer zones
• Use of artificial viscosity and explicit filtering to suppress parasitic waves
• Simulation of sound radiation and reflection/diffraction at walls
• Critical evaluation and sensitivity analysis of numerical results

What the module consists of

• PraktikumProcessing of 6–10 short projects for gradual introduction and application of numerical solution methods; creation of reports

Teaching method

• Projektarbeit mit MATLAB-SkriptenEnables practical testing of numerical methods and systematic evaluation of results
• Besprechungen und KolloquienDiscussion of solution strategies and problems to deepen understanding and promote critical appraisal
• Selbststudium des theoretischen HintergrundsDeepens missing prerequisite knowledge depending on the task
