BUG: channel395 and turbulentInflow/PCF: wrong length scale input

Summary

In the tutorials of channel395 and turbulentInflow/PCF, the integral-length scale input files (i.e. constant/boundaryData/inlet/0/L) involve length-scale values considerably lower (i.e. at least two orders of magnitude) than those indirectly reported in Moser et al. (1999).

In Moser et al., (1999), the integral-length scale information can be computed either by partially integrating the reported x-autocorrelations or by using the relation of k^(3/2)/epsilon on the reported resolved kinetic energy balance.

Both methods yielded similar values for length scales which revealed to be considerably higher in comparison to the length-scale info being used in the aforementioned tutorials.

The content of the available L files were computed by using the turbulenceFields function object on a given RANS simulation. This should have yielded comparable length-scale info, yet have not. This should also need to be inspected.
