Brayton Cycle Compare & Solve (BCCS) is a powerful, easy to use, and fast Brayton cycle simulator. Based in a MATLAB app, this tool will quickly perform the mathematical analysis of the Brayton cycle engine defined by the user. There are 3 different engine layouts to choose from with over 30 input parameters for the user to specify, allowing for vast customization. Users can specify the stage pressure ratios, fuel flow rates, component efficiencies, flight conditions, and more to define their engine. Most importantly, BCCS has built in tools to enable easy comparison and analysis of the results. Users can plot the T-s and P-v diagrams of their engines and view the thermodynamic properties at each engine station. In the other two plots the user picks which engine parameters to plot allowing them to explore the relationship between different parameters.
BCCS is perfect for classroom use; it was developed to bring an active learning experience into AE-5751 Advanced Air Breathing Propulsion at The Ohio State University. Students are able to explore the relationships between engine design and performance without being bogged down by the mathematical calculations. Keep an eye out for the upcoming publication which describes how this was implemented into the classroom, the effect on learning, and the student response to the whole experience.
Features
- MATLAB App for easy installation and access
- 1-D ideal and non-ideal analysis
- P-v and T-s diagrams along with 2 user defined plots
- Table of thermodynamic properties and performance parameters
- Engine diagram for quick reference to measurement locations
- Save, load, and share your engines
- Solve and compare as many engines as you want simultaneously
Where to Find
BCCS is free and available at the MATLAB File Exchange or installed directly in MATLAB using the "Get More Apps" button and searching for BCCS.
