AdemData es::adem(const double beta, const double delta_c, const double kappa, const double pi_coles, const double shear_ratio, const double u_inf, const double zeta, const EddySignature &signature_a, const EddySignature &signature_b, bool compute_spectra = true)

Compute full turbulent properties from given Attached-Detached Eddy Model parameters.

Uses the using the Lewkowicz (1982) formulation (Perry and Marusic eq.9) of the Coles wake function to determine u_h(z), spectra and Reynolds Stresses from input parameters.

Parameters
  • beta: The Clauser parameter, representing acceleration/decelaration of the boundary layer
  • delta_c: The boundary layer thickness in m
  • kappa: The von Karman constant, typically 0.41.
  • pi_coles: Coles wake parameter Pi
  • shear_ratio: Ratio between free stream and friction velocity S = u_inf/u_tau
  • u_inf: The free stream speed in m/s
  • zeta: Represents a scaled streamwise derivative of Pi
  • signature_a: EddySignature class loaded with data for type A eddies
  • signature_b: EddySignature class loaded with data for an ensemble of type B eddies
