The thesis is dedicated to the problem of improving the efficiency and reliability of technological topping the residual tops of sugar beet crowns taking into consideration the structural and technological parameters of an active type topper. The following aspects are theoretically researched: interaction of an active flat knife with the root beet crowns in mode of cutting with sliding; tensely deformed status of that knife when moving; model of moving the topper with active working bodies along sugar root beets rows; coefficient of sliding in the system “root – flat knife”. The dependence of sugar beet crowns cutting force by means of active flat knife on the working speed of a beet harvester, as well as on the knife reciprocating speed, knife blade thickness, root diameter, is developed experimentally. The corrosion effect of beet juice on functional capability of knife structural materials is researched. The use of active type topper design will improve the efficiency and reliability of toping the sugar beet crowns.

Повний текст джерелаThe purpose of this essay is to analyze the relations between the use of pace and representation of masculine intimacy. The music video to the song Territory by The Blaze is observed through a gender perspective in a film semiotic analysis. The method involves how intimacy is represented through non-verbal communication. The material will be analyzed through theories involving communication and gender identity to see how it is affected by pace. This leads to the result of a conclusion that slowing down the narrative contributes to a representation of male intimacy to have resemblance to how women are portrayed according to Mulvey’s theories about the Male gaze.

The offshore wind turbine will be influenced by the couple of aerodynamics and hydrodynamics.The selection of floating platform will directly affect the generating power of the wind turbine. The floating system of the OC3-Hywind and the OC4 DeepCwind is applied in this paper. Through the Blade Element Momentum theory evaluate the power curve of NREL-5MW wind turbine and compare to the NREL data. It shows two of them have similar power curve, but they have about 7.64% difference in the rating velocity condition. When we consider the real wind turbine control system in the pitch motion, the average power is no longer that high anymore. Within the motion of turbine, it causes the power of turbine have the same period as the motion of turbine. In this paper, coupling the Blade Element Momentum (BEM) and computational Fluid Dynamics model (CFD) to evaluate two type of floating wind turbine, spar and semisubmersible wind turbine. Under the wave height 4m and period 10s, it shows that the semisubmersible type floating wind turbine has lower power loss than the spar type of wind turbine. This simulation case is verified with the reference. According to this research present a suitable wave condition to reduce the power loss for both of the floating wind turbine. If the wave period is less than 8.4s, so the spar type floating wind turbine has been recommended. But if the wave period is larger than 10 s and the wave is just like calm sea state, the semisubmersible floating wind turbine will be better.

The purpose of this thesis is to build a wind turbine model and perform the motion simulation and dynamic analysis. In motion simulation part, we used FAST to model a 1.5MW, three-bladeed, up-wind, horizontal-axis wind turbine model and exported this model into ADAMS. ADAMS can generate a graphics output file which may be to view an animation of the motion simulation. The analysis results compared with FAST and ADAMS are obtained good agreements in this case. In dynamic analysis, we built a full-scale wind turbine blade model into the F.E.A software ANSYS, then applied the aerodynamic load which is from FAST analysis result into the blade we built. We could obtain stress distributions, deflections and nature frequencies of the wind turbine blade. It is useful for the construction of the methodology of designing and analysis mode for wind turbine blades.

In order to investigate the phenomenon that liner motion will become rotational motion when subjects fall. We use rectangular blades with different aspect-ratios and vary the angles of the blades in the experiment. We observe the effect of air resistance and the efficiency of the energy transformation on the aspect-ratios and the angles of the wings when the blades fall. We let the vanes with the aspect-ratio of 1.5:1, 1.75:1, 2.0:1, 2.5:1 and 3.0:1 collocated with angles of 30˚, 60˚ and 90˚ fall from 2.5 meters and observe the changing phenomenon of the motion. The result shows that, if we take the same blade and vary the angle gradually, the bigger the angle is, the slower the speed of rotation is. Besides, the resistance of the difference of the pressure to the blade goes greater, and the efficiency of the energy transformation increases. The blade with wider breadth of the wings takes much time to fall in a certain distance. Therefore, the falling speed slows down, the resistance increases, and the efficiency of the energy conversion goes down. Moreover, the rectangle blade with longer length of the wings takes much falling time. The falling speed goes slower, but the whirling speed is faster. So, the resistance causing the difference of the pressure increases and raises the efficiency of the energy transformation. It is found out the ninety angle between blades with aspect ratio of 2.5 has the highest energy conversion efficiency.

The purpose of this study is to investigate the deployment and recovery operations for Floating Kuroshio Turbine (FKT) in moored conditions, and those in ship towing conditions by applying the simulation software OrcaFlex. The hydrodynamic coefficients of each element of FKT were calculated by CFD tools of ANSYS-FLUENT and WAMIT. Then these results were introduced into OrcaFlex to set-up the numerical model of FKT, and the simulations of the deployment and recovery operations for FKT in moored conditions, and those in ship towing conditions were carried out. In order to improve the accuracy of simulations, the setting data for the rotor blades in OrcaFlex, which simulates blades performance basing on 2D element method, were modified to fit the more accurate blades performance obtained by 3D CFD method. In the present study, based on the FKT numerical model built by the modified 2D blade setting data and under the current speed conditions of 1.1 m/s to 1.5 m/s, we accordingly set up simulation scenarios of employing buoyancy engines to adjust water ballast for controlling the FKT’s ascending and descending for simulating the deployment and recovery operations. As the FKT develops to a certain extent, the towing test by ship in real sea must be first conducted. An analysis method to estimate the FKT’s towing force and submerged depth was proposed in the present study, and considered as the basis for cable length planning. Its validity was confirmed by comparing the estimated results with those obtained by OrcaFlex simulation. The results of simulation based on FKT numerical model with the modified blade performance show that the FKT can achieve the goal depth of the deployment and recovery operation in moored condition under the original capacity of buoyancy engines by adding proper ballast weight for the FKT. Moreover, the simulation results also show that FKT can submerge to proper depth in ship towing condition under the original capacity of buoyancy engines by adding proper ballast weight for the FKT
