Steady velocity formula
WebApr 14, 2024 · The velocity field u j is used for computations at the interface. At the interface, the function is defined as zero, and in Phase 1, the function is defined as positive, and in Phase 2, the function is defined as negative. The spreading of level-set function is computed by solving the convection equation and represented as: Webp = m v. You can see from the equation that momentum is directly proportional to the object’s mass ( m) and velocity ( v ). Therefore, the greater an object’s mass or the greater its velocity, the greater its …
