SUMMARY
The discussion centers on the design of gas turbine engine duct shapes, specifically the preference for convergent shapes over divergent ones. Convergent ducts maintain constant axial velocity while accommodating the increase in flow density. In contrast, divergent passages are utilized in turbines where density decreases due to expansion. This understanding clarifies the aerodynamic principles governing gas turbine design.
