Ethylene glycol is newtonian or non newtonian fluid?

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.

Surface tension on the interface between two fluids is a material property like e.g. density.

Yes in OpenFOAM, the details you can keep the thesis of Vuko Vukčević. It is well explained there
