Moving to engineering, but this is pretty specific. It might be best to seek their official support.Baybora said:A computational fluid dynamics program
A free surface is a fluid surface that is not attached to a rigid wall. It's like the upper surface of the water in a glass of water.Baybora said:What is the "plane of symmetry", "zero velocity wall" and "free surface" terms which I have seen in Polyflow? It says in Vnormal=Fs=0 for plane of symmetry and Vnormal= Vs= 0 for zero velocity Wall. Now I get when Vs=Vn=0 it means that the wall isn't moving and it's in a static state but didnt get what others actually mean in linguistics?
Thanks from now
A plane of symmetry in fluid dynamics is an imaginary plane that divides a fluid flow into two identical halves. This means that if the fluid flow is reflected across the plane, the resulting flow will be identical to the original flow. A plane of symmetry is often used to simplify the analysis of fluid flow problems.
A zero velocity wall in fluid dynamics is a boundary where the velocity of the fluid is equal to zero. This means that the fluid particles at the wall are not moving and have no kinetic energy. Zero velocity walls are often used in fluid flow simulations to model the behavior of real walls, such as walls of a pipe or a container.
A free surface in fluid dynamics is a boundary where the fluid is in contact with a gas or vacuum. This means that the fluid particles at the surface are not constrained by any solid boundaries and are free to move. Free surfaces are commonly seen in fluid flows involving liquids, such as rivers, oceans, and waterfalls.
Plane of symmetry, zero velocity wall, and free surface are all terms used to describe different boundaries in fluid dynamics. They are related in the sense that they all play a role in determining the behavior of fluid flow. For example, a plane of symmetry can be used to simplify the analysis of a flow with a free surface, and a zero velocity wall can affect the flow patterns near a free surface.
These terms are important in fluid dynamics because they help us understand and analyze the behavior of fluids in different scenarios. By defining boundaries such as planes of symmetry, zero velocity walls, and free surfaces, we can better model and predict the behavior of fluid flows in real-world situations. These terms also allow us to simplify complex flow problems and make them easier to solve.
