UEqn in cavitatingFoam
 
Hi,
I'm working on modeling cavitating flow around cylinder with different headforms.i try using cavitatingfoam,here in UEqn thing i don't understand

- fvc::div(muEff*(fvc::interpolate(dev(fvc::grad(U)) ) & mesh.Sf()))

Should it be "(fvc::grad(U)).T()" here?

or why didnt he put the following instead like other solver

+ turbulence->divDevReff(U)
any information is appreciated. Thanks in advance.
:D
