Scientists from Peking University, together with their American colleagues, have created a realistic method for 3D modeling of liquids.
In the new work, scientists have created a new approach to three-dimensional modeling of fluids: it accurately recreates surface tension.
Usually, the term “surface tension” means the surface tension of liquid bodies at the liquid-gas interface. In the case of a liquid interface, the surface tension can also be considered as a force acting per unit length of the surface contour and tending to reduce the surface to a minimum for given volumes of phases.
The authors note that in simple modeling systems only the effect of a solid body on a liquid is depicted, more complex systems take into account the mutual action of a body and a liquid on each other.
In the new method, the authors added a third component – a liquid surface tension membrane. The result is a realistic picture of how light objects lie on the surface of the water.
The system accurately simulates the weakening and strengthening of surface tension under the influence of chemicals, as well as the mutual attraction of bodies that float close to each other, but does not yet work on inhomogeneous liquids and porous bodies, for example, with a sponge.
