My guess is: Wall boundary = solid wall. (no slip, constant temperature, flux,etc)

outlet boundary = extrapolated boundary (reflective). when u can neglect boundary layer effects, i think u would more likely use this boundary condition

symmetry = as the name implies symmetry. to reduce computational time and resource
