Workshop 1: Numerical simulations for Wind Turbine engineering problems

28/6/2021 – 3/7/2021

Optimum blade design, structural dynamics, wind-structure interaction behavior, noise radiation, microseismicity, offshore and onshore foundations, fatigue damage estimation, corrosion & lightning protection and design of smart grids are some of the problems faced by engineers working in the emerging industry of wind turbines (WT). Thanks to significant advancements in simulation technology, WT engineers have available very powerful numerical tools for simulating all the aspects of the above-mentioned engineering problems.

The present workshop aims to provide a systematic presentation of numerical methods widely used for simulating WT problems. Methods like the Finite Element Method (FEM), The Finite Differences Method (FDM), the Method of Finite Volumes (FVM), the Boundary Element Method (BEM), Meshless and Meshfree Methods and hybrid methods that combine two or more of the above numerical methods, will be presented as useful numerical tools for treating WT engineering problems.

The workshop will take place in the Engineering School of the University of Patras from 28/6/2021 to 3/7/2021.
