Resumen

La Hidrodinámica de Partículas Suavizadas (Smoothed Particle Hydrodynamics, SPH) es un método CFD Lagrangiano sin malla (Mecánica de Fluidos Computacional, CFD). El método SPH frecuentemente utiliza partículas estáticas virtuales para corregir las deficiencias integrales que ocurren cerca de las fronteras. Estas partículas virtuales, aunque son útiles en la mayoría de los casos, pueden ser difíciles de implementar para objetos que experimentan grandes deformaciones. Como alternativa a las partículas virtuales, se presenta un algoritmo de fuerza repulsiva que emula indirectamente la presencia de las partículas virtuales en la ecuación de momento del método SPH.
