| Abstract | The operational characteristics of the Lev-Vection particle concentrator is studied. Maintaining a temperature differential between base and top in a body of liquid produces one or more thermal convection patterns. The requisite heat is supplied by an electric field applied across an array of interdigitated electrodes on the base. Levitation of weakly polarizable non-buoyant particles leading to a convective pattern among them is termed lev-vection. The particles become concentrated and trapped in a distinct area above the electrode plane. To improve efficiency of apparatus the effect of varying various parameters on speed and stability of induced circulation was examined. |
