This is a beta 1.8a version of the EngineSim program. If you find errors in the program or would like to suggest improvements, please send an e-mail to nancy.r.hall@nasa.gov. The software serves the need of different purposes from wind tunnel simulation to large wind turbines. We have looked at 6+ Wind Simulation tools which run on different platforms. We have seen tools run on mobile and tablets too. You can choose the simulation software you need and use it to do your analysis and work.
GT-POWER is the industry standard engine performance simulation, used by all major engine manufacturers and vehicle OEMs. GT-POWER is used to predict engine performance quantities such as power, torque, airflow, volumetric efficiency, fuel consumption, turbocharger performance and matching, and pumping losses, to name just a few. Beyond basic performance predictions, GT-POWER includes physical models for extending the predictions to include cylinder and tailpipe-out emissions, intake and exhaust system acoustic characteristics (level and quality), in-cylinder and pipe/manifold structure temperature, measured cylinder pressure analysis, and control system modeling. Standard GT-POWER engine models are easily converted to real-time capable models (also known as Fast Running Models – FRMs) for SiL or HiL simulations. These models may also be included in a full system level simulation within GT-SUITE to provide accurate and physically based engine boundary conditions to the rest of the vehicle.
