Overexpanded
WebWhen a flow is overexpanded, the lower gas pressure within the exhaust compared to that of the external atmosphere causes the exhaust to be compressed or squeezed inward. This … WebJun 4, 2011 · A direct, simple description is presented here. The four modes of nozzle operation are fully subsonic, normal shock in the diverging section, overexpanded, and underexpanded. They are defined by five values of back pressure , which are often expressed as the ratio of back pressure to supply stagnation pressure .
