We present a Bohm formulation for quantum fluid dynamics. Quantum potential and quantum force are calculated using fluid particles with gaussian shapes, in order to compute efficiently the space derivatives of the density involved. Some examples for simple system are presented as a test of the computational method. As a demostration of applicability, we study the excitation espectra of Na atoms attached to Helium droplets.
