Multi-disciplinary System Simulation for Model-Based Development

Customers share their success stories illustrating how Altair Model-Based Development technology, and especially Altair Activate™, help them design better products faster. These customers give special attention to simulating multi-disciplinary performance aspects of their products as a system-of-systems. Given the complexity of today’s smart products, this often involves a combination of mechanical, electrical & electronic, and/or software aspects – and thus leverages both 1D and 3D models simulated together.

Simulation of a Gas Turbine and Generator System Under Steady State and Transient Conditions using Altair Activate

Presentation by Tomas Suguinoshita Quirino, GT2 Tecnologia.

This work presents the strategy created by GT2 Tecnologia to simulate the dynamics of a system comprised by a gas turbine coupled with an electrical generator, which is a typical schema for thermoelectrical powerplants. The mathematical models of the gas turbine and the generator are based on physical principles, such as mass and energy conservation, as well as on correlations from the literature, including heat transfer coefficients and tables of thermodynamic properties. The models have been developed and tested in native languages (Fortran 90 and C++) and their integration with Altair Activate is achieved through the Custom C Block functionality. The system is first tested in Activate in a base load scenario, being then subjected to load changes. This work discusses the test results and shows the advantages of using sT Activate in the simulation of thermal and electrical phenomena.
