1D Parametric Analysis of a Centrifugal Pump
Hello everyone,
In this video, we will perform a one-dimensional analysis of a centrifugal pump using TurboTools. We will begin with the Vista CPD module, where you can size your impeller based on:
- Operating conditions
- Fluid properties
- Basic geometry of the impeller (blades, hub, and shroud)
You can also visualize some efficiency curves that are general trends based on empirical, non-dimensional coefficients.
Creating the One-Dimensional Analysis
Now, create the one-dimensional analysis, where the geometry and operating conditions will be transferred. The model takes a couple of minutes to run. Check the results for the set of input values you defined in the Vista CPD module. You will find some contour plots for variables like:
- Static pressure
- Velocity
- Tangential velocity
Analyze the distribution along the impeller.
Parametrization Process
- Start with the parametrization by selecting the inlet parameters in the properties section. In this demo, I select the mass flow rate.
- Next, select the output parameters from the expressions tab in the results. Here, I select all the efficiencies.
- Check the parametric analysis table. You will see several columns for input and output parameters.
- Once your input values are in the table, run the analysis.
Data Visualization
Finally, create some X-Y plots to understand the trends and identify the most convenient design point.
That's all for today. Thanks for watching. Please contact us at Ozen Engineering, Inc. for more information.
