It is common knowledge that one source of renewable energy can’t replace fossil fuel and it is necessary to adopt various renewable technologies. However, wind energy was not fully utilized. It is typically installed coastline or open rural areas and has a limited application that can be found near the urban area. The paper is developing a new design strategy to find an aerodynamic form of a pavilion that is optimized to generate on-site electricity with attached wind turbines.
Wind farms built in rural areas have the issue of energy losses and infrastructure like the cable construction expense for connecting from wind farms to cities is hard to avoid. Also, recently wind farms in open fields confronted with the waste problem. The blades are made of a pliable mix of resin and fiberglass. Decommissioned blades are also notoriously difficult and expensive to transport. They can be anywhere from 100 to 300 feet long and need to be cut up on-site before getting trucked away on specialized equipment.
For this reason, the paper is interest to investigate possible structures that can generate electricity in the urban area on a small scale. However, it is very difficult to utilize wind turbines around an urban area, because of the negative opinion on the appearance of wind turbines .
The paper proposes a structure that hides a wind turbine and able to generate electricity from wind. However, the most significant limitation of wind turbine applications in urban areas can be found in its complexity with surrounding site conditions. Unlike the open field, where no obstructions are nearby, it is comparatively easy to find the proper orientation of the turbine should face maximizing generating electricity. Since ground-level wind speed and directions vary by location, turbulent, low-velocity wind conditions it is difficult to design a wind turbine near an urban area. For that reason, further research must consider site-specific wind conditions that able to find better orientation, and the shape of the structure must be found.
The paper integrates advanced computational tools to find a form that maximizes electricity generation. Based on a parametric (Non-uniform rational basis spline, NURBS) modeling, the various geometries will be generated and passed to the (Computational Fluid Dynamics) to find a more site-specific wind condition for the whole year around. These performance outcomes are passed to the evaluation process where the objective functions determine whether the geometry satisfies the goal. If the objective function values don’t meet the requirements, the next population is generated based on the selection process and passed to parametric modeling to generate a new structure to evaluate the next generation’s performance. This loop continues until the goal is reached.
The outcome of the paper is demonstrating a design method that integrates different computational tools to find geometry that able to maximize site-specific wind potential to generate electricity and overcome the certain limitation of installing wind turbines close to urban areas.
