Use the Result Plot option to display either the wave profiles versus phase angle, wave velocity versus phase angle, or wave loads versus phase angle. The current is assumed to be parallel to the waves.

A relative heading of zero degrees is parallel to the structure, or ninety degrees is perpendicular to the structure. Wave and current heading is measured relative to the structure.

Wave and current loads are calculated at the center of the pipe. The Keulegan Carpenter number is calculated at maximum horizontal velocity (wave phase angle = 0). The phase angle for maximum load is calculated to the nearest degree. The maximum load is assumed to occur between 0 and 90 degrees phase angle. Wave spreading accounts for wave "choppiness". Wave loads can either be calculated from phase angle, or calculated for the maximum load magnitude. η : Wave Profile Height Relative To Sea LevelĬALCULATOR : Morison's Equation Horizontal Cylinder Wave And Current Loads Airy Stokes And Cnoidal Wave ±Ĭalculate Morison's equation wave and current loads on horizontal cylinders for Airy, Stokes and cnoidal waves.Φ : Force Heading Relative To Wave Direction.Use the Result Plot option to display either the wave profiles versus phase angle, wave velocity and acceleration versus phase angle, or wave loads versus phase angle.

The Keulegan Carpenter number is a measure of the ratio of wave inertial forces and drag forces. Lateral (lift) forces are due to non symmetric flow around the structure, either because of proximity to the seabed or another structure, or by non symmetric cross section. For horizontal structures the load forces also include vertical velocity and acceleration.
