Which location has the highest gas volume in a turbine engine?

The turbine outlet is recognized as the location with the highest gas volume in a turbine engine due to the processes that occur during the operation of the engine. As air flows through the engine, it is compressed at the compressor inlet and travels through the compressor sections, where its pressure and temperature are significantly increased.

Next, the compressed air enters the combustion chamber, where fuel is mixed and combusted, resulting in high-temperature gases. This combustion produces a notable increase in both temperature and volume as the gases expand rapidly. Ultimately, these high-energy gases then reach the turbine section.

After going through the turbine, the gas volume at the outlet remains high because of the large change in pressure and temperature experienced in the combustion chamber. The turbine extracts energy from these gases to drive the compressor and provide thrust. The volume at the turbine outlet reflects the exhaust gases that are expelled at high velocities after they have passed through the turbine, thus comprising the highest gas volume location in the system. This comprehension of airflow dynamics within the turbine engine is crucial for understanding its overall performance and efficiency.
