Hi @kkanade ,
For shallow water waves applications, the Froude number is used to define three flow conditions:
-subcritical (Fr<1), the water velocity < wave velocity, namely downstream conditions affect the upstream flow;
-critical (Fr=1), the water velocity = wave velocity, upstream waves remain stationary;
-supercritical (Fr>1), the water velocity > wave velocity, namely upstream flow is not affected by the downstream conditions.
Thank you! @Kremella
I have another question, Since the Froude number is defined as:
Fr = V/sqrt(g*L)
where V is the characteristic velocity, g is the characteristic external field, L is the characteristic length. What should I use for V, g and L?
In your case, V is the average flow velocity, g is the gravitational acceleration and L is the flow depth.
