Abstract

It is one of the challenging issues to simulate and visualize liquid behavior, especially the behavior of the viscoelastic fluid because it has both characteristics of viscosity and elasticity. Although Newtonian fluid, which sharing stress is proportional to the velocity gradient, is often analyzed with the ordinal governing equations that are Navier-Stokes equation and the equation of continuity, viscoelastic fluid behavior is so complex that there are no established governing equations, especially for the constitutive equation. Then, some studies used the Finite Element Method, and others developed a point-based method. In addition, the viscoelastic fluid has a unique characteristic called “Spinnability”. The fluid is stretched so long like a string and shrinks very fast when it is ruptured. Therefore, we have been performing viscoelastic fluid simulations based on Cauchy’s equation of motion by devising the stress term in the constitutive equation. In this paper, we report a viscoelastic fluid simulation based on the combination of viscous and elastic stresses.
