Hello everyone,

I am studting the thermal marangoni effect caused by the surface tension gradient. But in OpenFOAM, the tangential surface stress is not considered. Does anyone implement it in OpenFOAM?

The calculation of tangential stress is the last two terms in the figure. My idea is fvc::snGrad(sigma) - fvc::snGrad(alpha)*(fvc::snGrad(alpha)&fvc::snGrad (sigma))
But it is wrong. Does anyone have any idea? Thanks!
