Where is the highest gas volume found in a turbine engine?

In a turbine engine, the highest gas volume is found at the turbine outlet. As air enters the engine, it moves through the compressor, where it is compressed, then delivered to the combustion chamber. In the combustion chamber, fuel is introduced, and the resulting combustion process increases the temperature and pressure of the gases. After the combustion process, the gases expand and flow through the turbine, resulting in a decrease in pressure but an increase in gas volume due to the high temperatures generated during combustion.

By the time the gases exit through the turbine outlet, they have reached their maximum volume as they have expanded significantly. This is a critical stage in the engine's operation, as the expanding gases impart energy to the turbine, which then drives the compressor and other accessories. Understanding this flow of gas and pressure dynamics is fundamental for effective monitoring and control within a turbine engine system, making the turbine outlet a key area in terms of gas volume.
