Vortex Shedding around a SkyScraper building is analyzed for 2 designs at wind speeds of 45 m/s. Transient analysis for In-compressible Turbulent flow is performed. Building height is 150 m and cross dimensions 20 x 20 m.

This is a test of the use of wall functions with roughness length as Boundary Condition in a simulation of the Atmospheric Boundary Layer (ABL). The objective of this case (based in a case of Blocken et al.) is to observe the evolution of the velocity and turbulence parameters profiles and the the influence of the SimScale's characteristics on the quality of results.

This project is intended towards validating the turbulent flow around city blocks, in a configuration proposed by AIJ. This validation (Case C) consists in the comparison of the Flow Field at the equivalent pedestrian level between the experimental mesuarements (AIJ) and the SimScale results. The project considerates the problems of boundary conditions (Atmospheric Boundary Layer), mesh characteristics, turbulence models and the transient behaviour of the flow.

Experimental data: Turbulent Measurements of the flow field around a high-rise building. Meng & Hibi

This project simulates turbulent flow through a straight circular pipes with differents roughnesses.  Two turbulence models were used: kEpsilon and kOmegaSST. Simulation results from  were validated using the Moody Diagram.

Most renewable energy sources (including wind energy), including fossil fuel energy, comes from the sun. Overall, hourly, the sun provides the earth with over 175 Trillion kilowatt hour of energy. Of this energy, about 1-2 percent of this is converted to wind energy. The places on the equator are more directly heated compared to the poles. This leads to significant global wind systems. in addition, the local environment like the presence of cities, water bodies, forests alter the local wind profiles in any area. In the last decade, an emphasis on renewable energy sources and rapid growth of wind farms has led to significant decrease in associated costs.

The wind turbines developed in the 1980s became the breakthrough for the modern turbines. The wind rush that started in the 80s suddenly ended overnight when the California government stopped its support schemes. In the last decade starting 1998, the MegaWatt sized turbines and large wind farms have revolutionized the wind energy industry and making it a potent source of renewable energy. Spearheading this revolution has been Denmark and Germany, who are also the largest wind energy markets.

This project explores ideas for usage of SimScale and exploitation of its features towards design, simulation and optimization of the power output of wind farms.

Tutorial project for a flow analysis of a pipe junction. The project only provides the geometry to start with. See our tutorials section to have a look at the step-by-step instructions to set up the simulation.

How to simulate the airflow around a building is demonstrated in this project.
