Magnetic method for stimulating transport in fluids

DWPI Title: Method for transporting mass or heat in fluids, involves forming advection lattice which comprises anisometric magnetic particles for transport of mass or heat by fluid
Abstract: A method for producing mass and heat transport in fluids, wherein the method does not rely on conventional convection, that is, it does not require gravity, a thermal gradient, or a magnetic field gradient. This method gives rise to a unique class of vigorous, field-controllable flow patterns termed advection lattices. The advection lattices can be used to transport heat and/or mass in any desired direction using only magnetic fields.
Use: Method for transporting mass or heat in fluid.
Advantage: The natural convection in magnetic fluids is enhanced by applying a magnetic field gradient along the thermal gradient. The enhancement is dependent upon the thermal gradient and does not lead to new flow patterns. The low viscosity solvent reduces viscous drag and results in a better resolved advection lattice. The fluid properties have good heat capacity and thermal conductivity.
Novelty: The method involves providing a suspension of multiple anisometric magnetic particles in a fluid. A time-varying biaxial magnetic field is applied to the suspension, where the components of time-varying biaxial magnetic field are a time-dependent field having a frequency and the axes of the two components are not co-linear. An advection lattice which comprises the anisometric magnetic particles for a transport of mass or heat by the fluid is formed.
