Turbo Design 3

This tool is a streamline turbomachinery design tool solving the radial equilibrium equations. It can be used for designing compressors and turbines. The designs can have counter rotating stages, different working fluids, and cooling. The intent of this tool is to enable added flexibility in which loss models are used. Because it's a python, it can connect with custom machine learning based loss models.

Getting Loss Models working

Loss models need to be built. I have stored set of models on github as .pkl files. They should automatically download but depending on your python version, the pickle binaries may have issues reading.

Another way to generate them is to navigate to turbo-design/references/Turbines/AinleyMathieson (KackerOkapuu, Traupel, CraigCox) and run python build_dataset.py. This will create the loss models and save it to the .cache folder for Linux and Mac and for windows it will save to a different .cache folder in your home directory.

Examples

Turbines

OptTurb OptTurb is part of Paht's PhD work. It's a single stage HPT Turbine designed for Purdue's Experimental aeroThermal LAb (PETAL). It's an excellent candidate for verification because it can be easily modeled using a spreadsheet OptTurb-SingleStage.xlsx

OptTurb-multistage Multi-stage example of OptTurb. This is based off a meanline spreadsheet model OptTurb-MultiStage.xlsx

OptTurb-radial Radial Turbine Example. This example is not based on a meanline spreadsheet since radius is constantly changing. It still needs to be tested. It uses radial equilibrium to balance the massflow.

Building Turbine Loss Models from Correlations

The loss correlations below were estimated using Axial steam turbines. Correlation figures are extracted and surface fitted. Each of these tutorials shows how to create and save the correlation files.
