Abstract : The general problem of motion of colloid particles in a fluid flow due to an applied magnetic field may be stated as follows: Given a fluid flow with a known mass and volume fraction of colloids and with known velocity and number density distributions, to determine the manner in which the velocity and momentum of the two phases change along the direction of flow when a magnetic field of known orientation and strength is applied. Introducing a number of approximations (pertaining mainly to the distribution of the applied field, particle motion and particle agglomeration) the change in the momentum of the fluid is calculated for given applied fields and particle and fluid velocity and particle size distributions. The critical parameter of operation is the position in the field where the particles may come to rest. The influence of chosen system parameters on such a condition of operation was conducted and is expected to lead to an optimization study. (Author)
