dc.description.abstractTo summarise this thesis paper, I will briefly elaborate each of my major check points, and the results I obtained in and amongst all the research and simulations, as well as my own cognitive reasoning and understanding in the topic. Firstly, I introduce and explain what category of wind turbines the Darrieus type wind turbine is part of and which specific type of Darrieus Type Wind turbine. The Darrieus type wind turbine is categorised as a Vertical Axis Wind Turbine (VAWTs), this is due to the way it is set up unlike the usual wind turbines, they rotate around the vertical axis. More, specifically, I focused on the Helical shape of the Darrieus type wind turbine, as to eliminate inconsistency due to the curvature of the wind profile around the circumference of the wind turbine. This allows for a smoother output of torque and rpm that can be fed into the step-up gearbox, and finally, to the generator. Secondly, I ran simulations on the wing profiles I would think would be most suitable for the implementation into a Darrieus type wind turbine, and then perform the wind simulation using Ansys Discovery, to understand its behaviour in similar wind condition to as it would have, if it were to be implemented in the capital of Hungary, Budapest. The wind speed I found and used was 3.67m/s. The wing profiles I chose to perform my simulations on were the NACA 63(3)-618 and the NACA 0018, and compare the two against each other with each determining factor that would affect how it would behave if it were to be implemented on a Darrieus type wind turbine. I then performed multiple repeated simulations to make sure the results are consistent, and output the following data; Velocity, Total pressure and Static pressure. All the results pointed to the NACA 63(3)-618 being the more preferable wing profile between the two, due to its significantly higher value of Coefficient of Lift, and a negligible amount of slightly higher value of drag compared to the NACA 0018, which in fact maybe more useful as it may aid in rotations of the wind turbine as the wind passes by the wing profile. Finally, I compare my results to the literature already published and verify my results. My results show that the NACA 63(3)-618 is the more preferable wing profile, as there are many research papers published that note that they tested other NACA 6-series wing profiles and they performed really well to be used in a wind turbine and commercially is the shape mostly used for VAWTs and not the NACA 0018. Furthermore, my NACA 0018 performance data compares very similarly to the research paper from University or Stuttgart and University of Warsaw and this shows that there is a good level of accuracy between my work and other already published works, which shows that the simulations I have performed on the NACA 63(3)-618 are accurate and reliable. I also chose a well-fitting step-up gearbox and generator to go with the wind turbine design, thus making it theoretically plausible with the NACA 63(3)-618
