What is the Morison Equation?

The Morison equation is the sum of two force components: an inertia force in phase with the local flow acceleration and a drag force proportional to the (signed) square of the instantaneous flow velocity. The inertia force is of the functional form as found in potential flow theory, while the drag force has the form as found for a body placed in a steady flow. In the heuristic approach of Morison, O'Brien, Johnson and Schaaf these two force components, inertia and drag, are simply added to describe the inline force in an oscillatory flow. The transverse force—perpendicular to the flow direction, due to vortex shedding—has to be addressed separately.

How to Calculate Froude-Krylov Force?

Froude-Krylov Force calculator uses Froude-Krylov Force = Density of Fluid*Volume of Body*Flow Acceleration to calculate the Froude-Krylov Force, The Froude-Krylov Force formula is defined as the force introduced by the unsteady pressure field generated by undisturbed waves.
