B-Spline Impulse Response Functions of Rigid Bodies for Fluid-Structure Interaction Analysis

Wet surface solutions: (a) the BIRF of points on the “North Pole,” “Equator,” and “South Pole” due to B-spline flux at North Pole; (b) time history of the pressure field due to constant internal flux at specific points on the wet surface and comparison with analytical and other solutions in a nondimensional form where c is the pressure wave velocity, r is the radius of the sphere, t is time, p is the pressure field and q is the influx [23].
