As the gas flows through the turbine blades, it flows over and under each blade. The blades are shaped so that the gas goes faster over each blade than under each blade, and an imbalance of pressures results as a consequence of Bernoulli's effect. Each turbine blade acts like the wing of an airplane and experiences a lift force. This lift force pushes on each blade and twists the turbine around and around. The turbine blades effectively fly through the flowing gas stream and extract energy from it. The blades and turbine gain energy while the gas stream loses energy. The gas leaves the turbine at a lower pressure and/or speed than it had when it arrived.
