  1. PR and TR are the reservoir pressure and temperature, respectively. P, T, U, M, and \(R{e}_{\infty }^{U}\) are the freestream pressure, temperature, velocity, Mach number, and unit Reynolds number, respectively. \({u}_{\tau }=\sqrt{{\tau }_{w}/{\rho }_{w}}\), δ, Reτ = uτδ/νw, Reθ = ρuθ/μ, and Tw/Tr are the friction velocity, boundary-layer thickness, friction Reynolds number, momentum thickness Reynolds number, and wall to recovery temperature ratio, respectively.
