WebMean Velocity Profiles - Turbulent Boundary Layers: Near a solid boundary the flow has a distinct structure, called a boundary layer. The most important aspect of a boundary layer is that the velocity of the fluid goes to zero at the boundary. This is called the "no-slip" condition, i.e. the fluid velocity matches (has no slip WebUse the new Static Pressure type of Flow Boundary Condition simulation. object to model the fluid with a known static pressure at a location. The Static Pressure flow boundary condition acts either as an inlet or an. outlet depending on the physics of the model.
