Experimental research of thermal variations at sudden expansion of supersonic steam flow

Temperature effects evolving at discharge of supersonic steam flow into exhaust nozzle of large section are described. It is stated that in exhaust nozzle can evolve both local supercooling and local overheating of steam during which temperature exceeds temperature before nozzle in 5–10 °C. Hypothes...

Description
Summary:Temperature effects evolving at discharge of supersonic steam flow into exhaust nozzle of large section are described. It is stated that in exhaust nozzle can evolve both local supercooling and local overheating of steam during which temperature exceeds temperature before nozzle in 5–10 °C. Hypothesis is offered explaining this unusual phenomenon.
