how to find surface tension

[bujji]

Dear OpenLB team,
I’m trying to find the surface tension of fluids in multicomponent2D & multicomponent3D. In that code given input parameters as follows:

Code:

// Parameters for the simulation setup
const int nx = 400;
const int ny = 200;
const int maxIter = 20000;

const T omega1 = 1.0;
const T omega2 = 1.0;
const T G = 3.;
T force = 30./( T )ny/( T )ny;

Can you please explain how to find the surface tension of the fluids?

thanks in advance.

Hey bujji,

have another look at the book of Krüger et. al chapter 9.1.4, where the young-laplace-test is described. Besides multi phase simulations, this test case is also valid for multi component cases.

Best regards, Max

Hi Max,
Thanks for the quick reply
