|
Description
|
|
Computes U+ as a function of Reynolds number by inverting table of
|
|
y+ vs U+
|
|
|
|
Example dictionary specification:
|
|
|
|
tabulatedWallFunction general;
|
|
|
|
// Output table info
|
|
tableName uPlusWallFunctionData; // Output table name
|
|
log10 yes; // Re interpreted as log10(Rey)
|
|
dx 0.2; // Interval log10(Rey)
|
|
x0 -3; // Minimum log10(Rey)
|
|
xMax 7; // Maximum log10(Rey)
|
|
|
|
generalCoeffs
|
|
{
|
|
interpType linear; // Interpolation method
|
|
log10YPlus true; // y+ values defined as log10(y+)
|
|
log10UPlus true; // U+ values defined as log10(y+)
|
|
inputTable
|
|
(
|
|
(yPlusValue0 uPlusValue0)
|

...
|
|
(yPlusValueN uPlusValueN)
