Abstract

This paper presents the results of methodological studies aimed at investigating the ability to determine the position of the laminar-to-turbulent transition (LTT) using empirical criteria and numerical methods. The criteria of Simeonides and Berry have been investigated, and their results are compared with the experimental data and with the results of the numerical solution of the RANS equations with the transition turbulence model. Methodical studies were carried out for a flat plate, and for cones with different angles at the apex at zero and nonzero angles of attack. The studies were carried out in the range of Mach numbers M = 2 ÷ 10 and Reynolds numbers Re = (3 ÷ 45) ∙ 106 . Also, different methods for determining LTT on a complex surface of the HEXAFLY-INT glider model were compared.
