The computations are fulfilled in a sufficiently wide range of similarity parameters: 0.8 ≤ M ≤ 1.3, 103 ≤ Re ≤ 106 (laminar flow), and 106 ≤ Re ≤ 107 (turbulent flow). A streamlined surface is considered to be either adiabatic or isothermic with the temperature factor Tw0 = 0.5 (cooled surface) and 1.5 (overheated surface). The impact of the variable factors on the flow structure and aerodynamic characteristics of a circular cylinder are discussed.
