Fluid flows interacting with deformable wavy channel are simulated by a newly developed full-Eulerian simulation method. A single set of the governing equations for fluid and solid is employed. and a volume-of-fluid (VOF) function is used for describing the multi-component geometry. The stress field is defined by volume-averaging the stresses of the individual components through VOF. https://www.parisnaturalfoodes.shop/product-category/hot-choc-intensely-dark/
