Plasma Arc Cutting: Scientists Decode Gas Flow Dynamics

Curvature leads to shock waves, reducing gas flow velocity and plasma arc cutting process efficiency. Credit: Upendra Tuladhar, Busan National University Plasma Arc Cutting (PAC) is a thermal cutting technology widely used in manufacturing applications such as shipbuilding, aerospace, manufacturing, abolition of nuclear power plants, construction and automotive industries. This process involves high-speed ejection of plasma or ionized gases, and…
