Velocity Triangles Analysis
Read full descriptionHide full description
VTA app is a velocity analysis application of a turbomachinery stage. The user can easily extract useful results and velocity diagrams by importing some dimensionless sizes, input-output angles and general geometric features. This application gives also the ability to compare cases with different input parameters. Through a quick and easy analysis of the velocity triangles inside a turbine or a compressor the student could experiment and thus gain a deeper understanding of the operation of an energy system. It has been developed for education purposes.
