Hi Guys. This is for my post graduation project. I came across a turbine performance map where the turbine specs are mentioned as GT12, 72 Trim, 0.39 A/R. Now what exactly these terms means. Please help.
Thanks alot.. but what is 72 trim ?zAbso said:GT12 is the model (Galvanized Turbine), 0.39 Area/Radius

I have family that works for a manufacturer, maybe this link will help you if I'm thinking of the right thing.
Thank You. I have data for a two wheel bootstarp air cycle machine used in aircraft environmental control system for air-conditioning under working conditions. The data is for different flight conditions, different temperature and pressure. I want generate corrected mass flow rate vs pressure ratio curve of the turbine used in the system. I don't have the standard data noted at STP (standard pressure and temperature) conditions, and no manufacture provided performance curve, but can I generate a curve using the available values which is not taken under STP conditions.zAbso said:http://turbobygarrett.com/turbobygarrett/wheel_trim
This should explain what trim is, I only briefly read over it but it should help.
Turbine performance notation is a standardized way of representing the performance of a turbine. It includes important parameters such as flow rate, pressure, and efficiency, and is used to compare the performance of different turbines.
Understanding turbine performance notation allows scientists and engineers to accurately assess the efficiency and effectiveness of a turbine. It also helps in making informed decisions about which turbine to use for a specific application.
Turbine performance notation is calculated using various equations and formulas that take into account the input and output parameters of the turbine. These include the mass flow rate, inlet and outlet pressures, and temperature.
There are several types of turbine performance notation, including isentropic efficiency, polytropic efficiency, and adiabatic efficiency. These notations differ in the assumptions and calculations used, but all aim to measure the performance of a turbine.
Turbine performance notation plays a crucial role in turbine design as it helps engineers determine the optimal specifications for a turbine that will result in the desired performance. It also allows for the comparison of different design options to find the most efficient and effective turbine.
