Interest in microfluidics has led many potential benefits in the current technological engineering. The acoustic waves at ultrasonic frequencies have been used to process and separate small particles of different densities and compressibilities laboratory using integrated microdevices. The separation of particles in microfluidic systems been has demonstrated by use of centrifugation, magnetophoresis, hydrodynamics dielectrophoresis and acoustophoresis. The acoustophoresis is a technique that allows separation of microparticles in suspension using acoustic radiation force. Creating within the fluid microcamera one fundamental resonant mode nodal provides a sound pressure field, for particle separation to occur there must be a difference between the physical properties of density and compressibility, leading to a lateral displacement in the trajectory of particles in a laminar new trajectory defined. This method is remarkably advantageous as it requires no pretreatment of the particles and applied can be to virtually all types of particles. The magnitude of the acoustic radiation force exerted on the particles no damage on them, due to their magnitude of periodic action and response produced in the conductive fluid medium. As the acoustic radiation force exerted, leading to internal motion of particles in the fluid and their eventual discharge along a predetermined path desired to be brought into resonance effect the microchamber and trajectory equations describing the particle displacement and determining the final concentration based on computer simulation. It also makes the comparison of computer simulation with experimental data have been obtained by this technique at the University of Southampton, University of Lund. This raises the action of the actuation frequency of the acoustic radiation force and finally the separation of constituent particles of the blood erythrocytes and lipid through computational simulation and compared with the data and photographs were obtained at the University of Lund.
