Integrating wind turbines on skyscrapers

As for the civil engineering aspect, the problem was where to position the wind turbine and the loading the structure will have to bear incase of any additional loading.

Solution

Solution1:When building a structure, a factor of safety must be taken in consideration to account for any additional loading

First of all, we measure the loading effect of the turbines we are going to install.

We analyze the data we got for the loading effect and we make sure that it is well positioned

Finally after the analysis stage we check if its safe and based on that we decide whether to install it or not.

Solution 2:Another solution proposed was to replace the generators on the rooftop with the wind turbines however incase of failure we will not have an alternative source of energy.

The first two solutions (interviewed the professor) so cite the professor here.

From the article cite it please (paraphrase- use these points) identify the main requirements of a suitable installation site are provided in technical literature

The CFD results and the developed model to account for the performance variation due to the skewed flow were combined in order to perform a feasibility analysis of an H-Darrieus installation in the rooftop of a building in the built environment.

As a first step, a study turbine was designed, whose main features are reported in Table 4: (include the main features of the study turbine in the article) the H-Darrieus scheme was adopted (Fig. 10 include the figure) and structural and dimensional constraints, which could be compatible with a rooftop installation, were taken into account in designing the machine (see [23]); in particular, due to the high rotational speeds of these rotors, thick supporting struts and auxiliary tie-rods have been included in the model in order to resist the centrifugal loads acting on the blades.

Conclusion of the article A wide-ranging analysis was carried out to evaluate the energetic suitability of a Darrieus VAWT installation in the rooftop of a building in a reference European city. With this goal in mind, the first step of the analysis consisted on a numerical CFD analysis to characterize the flow field in the rooftop area

Finally, the results of the CFD simulations and the new turbine model were combined in a comparative feasibility analysis of a medium-size H-Darrieus turbine in the built environment.

The analysis showed that notable increments (up to 70%) of the attended capacity factor in the rooftop area of an installation building in the urban environment can be achieved whenever a building reasonably higher than the average of the surrounding constructions is selected and suitable geometric proportions of the building itself with respect to its upwind building are fulfilled

Evaluation

Based on calculations done,This table displays the cost analysis comparison between the use of conventional wind turbines versus the flodesign.The only difference between them is in the blades material. As for the weight, the conventional turbine is much larger than the flodesign due to the size as seen in this picture.  However the cost of the flodesign is almost 11 times higher than the conventional turbines due to the use of helical gears. For the total rotor cost we calculate it by multiplying the weight by the cost

Include a small part for the recommendations (paraphrase everything pleaseeee)

• Focusing research on integrating flodesign turbines” on skyscrapers
• Looking for techniques to increase the efficiency of the flodesign turbine
• Investigating different materials that enhance the reliability and strength of turbines
• Carrying out a complete cost analysis of the flodesign versus the conventional turbines
