Prof. Dr. Georg Pingen - Introduction to Topology Optimization for Fluids

Department of Engineering Union University, USA

Abstract

The short course will provide a practical introduction to topology optimization for fluids. Attendees will be provided with a functional MATLAB based flow topology optimization algorithm using the lattice Boltzmann method and a sequential convex programming (SCP) based optimizer. The focus of the short course will be on fundamental aspects of flow topology optimization such as boundary representations and the adjoint sensitivity analysis. The fundamentals will be presented using the problem of drag reduction for an object placed in a low Reynolds number flow. Attendees will be encouraged to experiment with other problems following the short course. Further, we will consider the mathematical formulation of the adjoint sensitivity analysis and possible alternatives for its solution. To conclude, we will briefly discuss current challenges in flow topology optimization.
