Understanding Superheater and Supercritical Boiler

This boiler is called supercritical because it operates above the critical pressure and temperatures, which is 3,200 psi and 647 Kelvin. In contrast to a superheater boiler that requires a device to separate water vapor with a mixture of steam and water (usually called steam drum), supercritical boilers do not need it.

Supercritical airfoil - Wikipedia

2020-6-5 · A supercritical airfoil is an airfoil designed primarily to delay the onset of wave drag in the transonic speed range. Supercritical airfoils are characterized by their flattened upper surface, highly cambered ("downward-curved") aft section, and larger leading-edge radius compared with NACA 6-series laminar airfoil shapes. Standard wing shapes are designed to create lower pressure over the
