Effect of scale size on a rocket engine with suddenly frozen nozzle flow [PDF]

open access: greenARS Journal, 1961
Recent analytical work by Bray indicates that single element, chemically reacting systems, e.g., H_2 ⇋ 2H, may suddenly freeze their composition at some point in a high speed nozzle and then remain at fixed composition throughout the remainder of the

Effect of Convergent Section Contour on the Sonic Line in Rocket Engine Nozzles

open access: goldJournal of Aerospace Technology and Management, 2018
This study made a numeric evaluation of the effect of convergent geometry on the position and profile of the sonic line in rocket engine nozzles. To validate the numerical solution, two conical nozzles, from which experimental results are available in the literature, were used as reference.
