The aerodynamic design of high Mach number nozzles utilizing axisymmetric flow with application to a nozzle of square test section

From Introduction: "A method for the design of three-dimensional nozzles based on axi-symmetric flow is presented in this paper. The design method presented in this paper is general; however, as an illustrative example of the design of a Mach number 10 nozzle with square test section is included."
