22 Case study of World Trade Centre Bahrain 2
World Trade Centre Bahrain has an amazing design which is the wind turbines. The generator windmill has a rotor speed of 38 revolutions per minute at full load and is powered by a series of gearboxes placed in the engine compartment to run the generator at 1,500 revolutions per minute. The optimal power generation design is approximately 225 kW at a wind speed of 15-20 m/s. Moreover, the fan rotor has a diameter of 29 meters and is made of 50 layers of glass fibre. When the wind is strong or needs to be transferred to a standstill state, the top of the fins will be pushed outwards, increasing the total torque of the rotor and achieving the purpose of deceleration. To protect the building from the natural disasters. The maximum wind speed that the wind turbine can withstand is 80 meters per second, which means it can withstand Class 4 hurricanes.
There are some really difficult challenges when this building is building. The first challenge is the design of wind turbine impellers between twin towers. The wind turbines of general wind power plants are all placed on straight rods to facilitate the impeller to maintain its windward condition. The rotating surface can also be steered in time with the deflection of the wind direction. The design fixes the rotating impeller in a horizontal position and cannot be moved after being fixed. Naturally, the rotating surface does not want to adjust the direction of the wind. Furthermore, being unable to adjust with the wind means that it is not possible to guarantee a positive windward state for a sufficient period of time, and the corresponding energy production will also be reduced.
To solve this challenge, introducing a streamlined triangular building design, which can use the principle of air flow to guide more high-level airflows to lower altitudes, reduce the wind strength of high-level wind turbines, and transmit more wind power to lower-level wind turbines. After precise calculations and airflow simulations, the design ultimately ensures that the three wind turbines maintain substantially the same speed of operation and that the electrical energy produced remains within the same standard.
