Detailed Description

Computes U+ as a function of Reynolds number by inverting Spaldings law.

Example dictionary specification:

tabulatedWallFunction SpaldingsLaw;

Output table info tableName uPlusWallFunctionData; // Output table name log10 yes; // Rey interpreted as log10(Rey) dx 0.2; // Interval log10(Rey) x0 -3; // Minimum log10(Rey) xMax 7; // Maximum log10(Rey)

SpaldingsLawCoeffs { kappa 0.41; // Von Karman constant E 9.8; // Law-of-the-wall E coefficient }
