The deformation and breakup of a droplet in two phase shear flow are simulated by the finite difference lattice Boltzmann method (FDLBM). The fine particle formation process in a medialess nanodisperser using ultrathin film and high shear is investigated. As a result, the critical Capillary number <I>C<SUB>ac</SUB></I>, is found under a constant Reynolds number, <I>R<SUB>e</SUB></I>. The necessary condition for the creation of fine particles by the disperser is <I>C<SUB>a</SUB></I>><I>C<SUB>ac</SUB></I>. Based on the <I>C<SUB>ac</SUB></I>, the atomization ability of the disperser is discussed. Simulation results demonstrate that the disperser can be used to form nanoparticles.
