Results
- Analytic solution for x direction flow
- assume uniform flow
- y velocity = 0.0
- change in u velocity with respect to x = 0.0
= -2.0988e-6 m/m
- AdH computed slope = -2.0933e-6
- Velocity shows a curvature to the right which is supported by Coriolis theory
- Analytic solution for y direction flow
- assume uniform flow
- x velocity = 0.0
- change in v velocity with respect to y = 0.0
- water surface slope is again = -2.0988e-6 m/m
-
- AdH computes slope = -2.0357e-6
- Velocity shows a curvature to the right which is again supported by Coriolis theory
