WebFluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented with streamlines showing the direction the water flows in different areas. WebMar 15, 2014 · They assumed the flow as steady, turbulent and incompressible. The turbulent flow by the revised model was adopted to calculate effects of low Reynolds numbers near the wall. Marx [13] implemented the implicit MUSCL scheme to calculate 3-D compressible Navier–Stokes equations.
