- ItemVariabilní měřící prostor pro supersonický aerodynamický tunel(Technická Univerzita v Liberci, 2011) Stupka, Oldřich; Dvořák, VáclavDiploma thesis deals with design, construction and testing of a variable test section. For its initial operations, three different nozzles for Mach numbers 1.4, 1.8 and 2.2 were made. These nozzles were designed using the method of characteristics. A Part of this work was to design and build a program to calculate the shape of jets using this method. Proposed profiles were simulated in software Fluent to verify the validity of the method of characteristics. During the experimental measurements in the laboratory of high speed in the Institute of Thermodynamics AVČR, images of the flow field using the colour schlieren method was taken. These were compared with numerical simulations and calculations using 1D method.
