Characteristics of Wind Turbine Noise

Noise generated by a wind turbine can be categorized into two types: aerodynamic noise and mechanical noise. The primary sources of mechanical noise of the turbine are gearboxes, bearings, and accessories. Due to technical advancements, mechanical noise is reduced to the extent that it is not considered a significant noise source from the turbine as it previously was. However, the aerodynamic noise produced due to the interaction of the airfoil blade and the boundary layer around it is still a significant source of noise.

Computational Fluid Dynamic Simulation - Pipeline T-Junction

Fluid flow in a T junction – sounds simple right? However, it can be more challenging than one might expect. Sharp T-junctions (shown on the left) have been known to cause issues in the pipeline industry. With abrasive materials transported through these pipes, they are damaged and corroded, thereby leading to high replacement costs. With a smoothed junction (shown on the right), the severity of the flow is reduced, which alleviates the problem. To learn more on how to model such systems – feel free to contact ENA2!

Finite Element Analysis Simulation
Drill Bit

Drilling operations produce enormous stress on a drill bit. This is due to the conditions of the rock and/or soil it is drilling through as well as the speed by which it rotates and moves. Therefore, optimization of the bit geometry is of utmost importance to minimize stress concentrations. At ENA2, we use finite element analysis (FEA) to examine the behaviour of drilling equipment. It is our goal to provide cost-effective solutions which are reliable and long lasting. If you have any questions or want to learn more feel free to contact ENA2!

Seismic Analysis Simulation Just BioFibre Home

Using Dlubal Software, a seismic analysis was completed on a house in Victoria, BC that was constructed from Just BioFiber Structural Solutions blocks. Just BioFibre blocks are a revolutionary building material that are carbon negative (decrease the overall amount of C02 in the atmosphere). The animation displays the deformational behaviour of the house if it were to be subjected to an earthquake.
