Civil Engineering case study

Simulation of the solar power plant construction loading under strong wind

In January 2013 we did an interesting project dealing with solar power plant construction loading under strong wind conditions. Our customer, the developer of the solar power plants, wanted to analyze the risks connected with problem the plants are facing strong wind conditions. The aerodynamic forces and torques acting on the power plant construction are enormous.

The customer was deciding between experimental measurement and CFD simulation. Due to the fact that the measurement was not possible in measuring scale 1:1 (not all variables and dimensionless numbers would be preserved, especially Mach and Reynolds number) customer finally decided to go for CFD simulation.

The aim was to compute the forces and torques acting on the power plant construction under different angles of attack, different elevation angles and different wind speeds. The other aim of the project was to determine the ideal position (elevation, rotation) to minimize forces and moments when extreme conditions come.

We have developed methodology for solving incompressible turbulent fluid flow with extra emphasis on forces and torques acting on structures. A special care was taken while testing various turbulence models to get uncertainty coming from turbulence model. Another big effort was to eliminate case grid sensitivity using mesh sensitivity tests.

Altogether we have run hundreds of single simulations to catch all the requirements and physical and numerical phenomena. The customer received deep CFD study of the solar power plant construction loading under strong wind conditions.
