What is the term for the increase in velocity in gas turbine systems?

The term "acceleration" is used to describe the increase in velocity in gas turbine systems. In the context of gas turbines, acceleration refers to the process by which the flow of air or combustion gases speeds up as it passes through various components of the turbine, such as the compressor and the turbine blades themselves.

When the working fluid enters the turbine, its kinetic energy is increased through mechanical processes, resulting in higher velocity. This increase in velocity is crucial for maintaining efficient combustion and maximizing power output in the turbine system. Understanding acceleration is vital for technicians as it directly impacts the performance and efficiency of the gas turbine.

The other terms presented do not accurately capture the concept of increasing velocity within gas turbine systems, as they refer to different phenomena or aspects of motion.
