Centrifugal Pump Design with Ansys TurboSystem - Part 1
Hello, and thank you for joining this video from Ozen Engineering, Inc. Today, we're going to start building a centrifugal pump design from scratch and take it through the entire analysis process using ANSYS tools.
Initial Setup
For this purpose, I've opened up the latest Workbench version. I'll navigate to the component systems and select Vista CPD for centrifugal pump design.
Blade Design
We will begin by designing both the impeller and the volute around it. Let's start with our impeller:
- Select the impeller at the top.
- Define operating conditions:
- 1600 RPM
- 300 cubic meters per hour of water flow
- Leave the rest of the inputs the same. If the user has efficiency data, it can be adjusted here.
Geometry Adjustments
Next, we move to the geometry tab:
- Change the diameter factor and the diameter ratio.
- Keep the trailing edge blade angle the same.
- Increase the number of blades to eight.
Results and Preliminary Shape
Proceed to the results tab and hit calculate. The software will generate a preliminary shape for our impeller. Here, we can view the properties and performance of our impeller. The efficiency chart looks good and is within the expected data range, so we can proceed with this impeller design.
Volute Design
We also want to design our volute:
- Check the volute option.
- Operating conditions remain the same.
- No changes to geometric inputs are necessary.
- Hit calculate to generate basic parameters and shape for the volute.
Improving Impeller Design with BladeGen
Once this step is complete, close the current window and proceed to BladeGen to refine our impeller design:
- Double-click on BladeGen to open it.
- BladeGen is a tool developed for turbomachinery design engineers, allowing quick design changes.
- Today, we'll make a small change by adding a more rounded trailing edge:
- Click the blade properties button.
- Adjust the trailing edge to an ellipse.
- Observe the immediate change in design on the graph.
BladeGen allows for adjustments to blade thickness, curvature, and hub and shroud shapes, but we won't explore these options today. Close the BladeGen window when finished.
Thank you for following along with this part of the centrifugal pump design process.
Centrifugal Pump Design with ANSYS TurboSystem - Part 1 Hello, thanks for joining this video from Ozen Engineering. Today, we're going to start building a centrifugal pump design from scratch and take it through the whole way through the analysis using ANSYS tools.
For this purpose, I've opened up the latest workbench version and then I'm going to go under Component Systems and I'm going to pick Vista CPD for centrifugal pump design. And there we have, we're going to first start looking at the blade design.
We will be designing both impeller and the volute around it. So let's start with our impeller. We have impeller selected up top and we need to define our operating conditions, which are 1600 RPM. Let's put in 300 cubic meters per hour of water flow.
We are going to leave the rest of the inputs the same. If the user has information on some efficiencies, it can be changed over here. So, let's move on to the next tab, which is the geometry. Let's change the diameter factor and the diameter ratio. Let's keep the trailing edge blade angle the same.
Increase our number of blades to eight. The next step is, we go to results and when we hit calculate, the software is going to generate the results. We're going to see that the results are the same. So, let's just create a preliminary shape for our impeller.
And here, we can see the properties and performance of our impeller. Let's look at our efficiency chart, which looks pretty good. It's within the expected range of data. So, we can start with this impeller design. We also want to do our volute design here.
So, let's check volume and, the operating conditions are the same. And we really don't want to change any of the geometric inputs here. So, we can just hit calculate and it's going to come up with some basic parameters and shape for the volume. Okay. Okay. Okay.
Once we're done with this step, we can hit the close button. Now, let's go to blade gen and improve on our impeller design. So, we're going to double click on it and let's move our window here. Blade Gen is a tool that is developed for turbo machinery design engineers.
It gives the user power to change the design very quickly by clicking on these buttons and you can make changes many different ways. Today, I'm just going to make a small change. I'm going to put on a more rounded trailing edge. So, for that, I'm going to hit the blade properties button here.
You can essentially play with different leading and trailing edge options. So, I'm going to go to trailing edge and I'm going to check ellipse. I'll hit okay. And you're going to see the change in design immediately in the graph here. Okay.
So, this is a pretty powerful tool where you can change the thickness, curvature, etc., of the blades or play with the hub and the shroud shape. But, I'm not going to be doing that for today's example. So, I'm just going to close this window down. Let me close this window down.
Did I read that exactly right? Yeah. Oh, um, So here's what I do. Let me put the screen on. I'll sweeten by a few clicks. Um,
