To achieve an accurate outline shape of a turbine blade a good cheat is to import a profile drawing of one into the Solid Works sketch then sketch over it tracing its curves using splines and lines. Use the image attached or another image or the desired blade. Resize the image to the size of blade yo want To make it easier to draw round the shape of the blade it is a good idea to split it into 6 sections using the linear sketch pattern.
Where the vertical lines cross the outline of the blade insert sketch points. You can then delete the lines leaving only the sketch points Using the spline tool you can draw round the outline of the shape Use the arrows to adjust the lines to fit the outline of the picture once you have done this you can delete the picture leaving only the outline.
Using the sketch points as reference add a new drawing plane. Step 3 - drawing the top curve Select each plane individually and draw on the cross section of the blade at this point. Some times it is useful to insert a picture to draw around. For mine sketch on plane 1 simply consist of a semi-circle to reflect it being the end of the blade that is attaches to the turbine Hub.
I used spline lines with around 4 points to each, making them easier to manipulate to the desired shape and curve. You can either do the top section and bottom section as different sketches or do them as one sketch.
I would recommend yo do them as one sketch as it makes it easier when it comes to filling in the rest of the shape. There are 2 ways to do the next step and it depends on what type of 3D printer you are using. By blossomsPDE Follow. More by the author:. Add Teacher Note. Did you make this project?

The whole tutorial is divided into two parts: 1. Modelling the blade profile 2. Pattern the blade profile and model the shaft.
Lets start. This command works only on 2D circle sketches and transforms them into a 3D spiral or helix sketch. Take a look at figure number 3 below to better understand this step of the tutorial. You will see a random helix generated but you need to define it correctly. Here, I use 0. Make sure that the revolution value should be 1.
Explaining this tutorial might be a bit challenging. See the figure below to understand this step visually and better. For a better understanding of the matter, take a look at the image here, where I assign the name to all three lines which makes it easier to understand this surface loft process. Right after a new popup menu will appear with five selection icons.
Choose the third icon which allows you to select a single entity from the complete sketch. When we select these two entities a triangular surface generates. Pay attention to the figure below to understand this step of the SolidWorks tutorial better. To get the conical spiral shape you need to select the existing blue spiral as a guide curve just by simply clicking on it. After selecting the helix we get the perfect shape of the blade and to execute this operation hit the green checkmark.
To clear any doubts, take a look at this image here to grasp a more accurate vision of this step. Continue by selecting the existing surface and creating an outward thickness of 10 mm. Take a look at this image for a clearer understanding of this explanations. At this stage, you need to create some fillets on the sharp edges of your turbine. Note these fillets are completely optional and you do not have to necessarily make them.
Select the top small edge of the blade and assign a 30 mm fillet radius and click OK to exit the fillet menu by hitting the green checkmark from its Property Manager. See figure 11 below to better understand this action.
In this step, we are going to more or less repeat the last action a multiple times which was voluntary. Therefore, this move will also be optional. But, I recommend you to create them to make your turbine and its blade more realistic. Add some more fillets on the outer curved edges and assign a fillet radius of 3 mm.
After that, the modelling of the turbine blade profile is completed and we have to proceed to the next step. But first, we must model the shaft, which further is used as a reference for the circular pattern.Have you ever wondered how a wind turbine model is created using SolidWorks?
Solidworks tutorial | Sketch Wind Turbine in Solidworks
Most people are intimidated by the idea of creating wind turbine models using SolidWorks. To get an idea of how outsourcing a wind SolidWorks turbine model works, you need to first understand SolidWorks and its function. A computer-aided design CAD program that runs on Microsoft Windows, SolidWorks allows engineers and designers to create custom designs with precise specifications and dimensions. Everything is explained below:. There are certain steps necessary to design a simple turbine model.
A turbine is a machine that captures energy in fluid flow and directs that energy to other devices. An essential part of turbines is turbine blades. The blades are attached to a rotor that is connected to a shaft. The shaft spins when a turbine is exposed to moving the fluid. The shaft then transmits power to other devices. The blades of a turbine are shaped to efficiently harness the energy in a flow field.
The purpose of this is to create end designs based on the preference of the user. There you have it—an overview of how outsourcing a wind SolidWorks turbine model works.

To Shop To Cart.Hi Fahad, Where did you get the data of the wind turbine experimental power? I've been searching the data from some papers and publications but they only give graphs instead of exact number of experimental tower.
SolidWorks Videos. The time derivatives are approximated with an implicit first-order Euler scheme. To predict turbulent flows, the Favre-averaged Navier-Stokes equations are used.
The subscripts are used to denote summation over the three coordinate directions. All the simulations were performed to predict three-dimensional transient flow over the wind turbine. To ensure validation of the numerical methodology, the numerical results of the present study were compared with the experimental results. A total of six tip-speed ratios were selected for the present study, as mentioned in table 1. The diameter of the wind turbine is Table 1; TSR and the corresponding wind speeds.
Wind Speed [ms -1 ]. The comparison between the experimentally determined shaft torques and numerical results of the present study, along with the number of mesh cells and the time step employed at various wind speeds is shown in table 2.
The computational domain selected had a size of 4Dx4Dx2. The computational domain had a large enough volume to accurately trace the fluid flow around the wind turbine and for the solver to operate without any reversed flow or unwanted vortex formation or any other numerical difficulties.
The resulting mesh, employs the immersed boundary method, has three types of cells, namely Fluid cells; the cells located entirely in the fluid, Solid cells; the cells located entirely in the solid and Partial cells are the cells which are partly in the solid and partly in the fluid .
The Cartesian mesh with immersed boundary method has certain advantages, like the mesh is very quick to generate and results in high quality elements. The solution converges faster and the mesh distortion and numerical errors are relatively lower. During the process of mesh generation, it was made sure that the region of interest; the region immediately surrounding the wind turbine; had a very fine mesh as compared to the boundaries of the computational domain, to make the simulations converge.
