Input

ESDU CFM calculates the local and mean skin friction coefficients for a turbulent boundary layer on a smooth flat plate with zero pressure gradient.

Full details of the Derivation of the method and its application are given in ESDU 68020 in the ESDU Aerodynamics Series.

Reynolds Number based on distance measured from virtual origin of the turbulent boundary layer | |

Mach number at edge of boundary layer | |

Mean skin friction coefficient | |

Local skin friction coefficient |

See Eqn (A2.5) from ESDU 68020.

Mach number must lie in the range
$$0 \le M_{1} \le 5$$
