A one-parameter family of interpolating kernels for smoothed particle hydrodynamics studies
چکیده انگلیسی

A set of interpolating functions of the type f(v)={sinπ2v/π2v}n is analyzed in the context of the smoothed-particle hydrodynamics (SPH) technique. The behaviour of these kernels for several values of the parameter n   has been studied either analytically as well as numerically in connection with several tests carried out in two-dimensions. The main advantage of this kernel relies in its flexibility because for n=3n=3 it is similar to the standard widely used cubic-spline, whereas for n>3n>3 the interpolating function becomes more centrally condensed, being well suited to track discontinuities such as shock fronts and thermal waves.
