Convective boundary condition using average velocity

I am trying to create a convective boundary condition for my LES jet flow problem. Although other user written boundary condition are available in this forum, I am trying to implement a BC which uses the average velocity of the patch as the convective velocity.
I decided to modify the advective boundary condition, which uses the local flux to calculate the convective velocity. I just modified the portion which calculates the advection speed(convective velocity). The below code is compiling without errors. Is it correct.
Foam::convectiveFvPatchField<Type>::advectionSpeed () const
const surfaceScalarField& phi =
fvsPatchField<scalar> phip =
this->patch().template lookupPatchField<surfaceScalarField, scalar>
phipt = Foam::gSum(phip); //****** Line one ******//
const scalarField& areap = this->patch().magSf();
scalarField area(areap.size(),Foam::gSum(areap)); //*** Line two ***/
In line one can I equate a surface scalar patch field to a surface scalar ?
Is line two correct ?
