Enhanced boundary layer heat transfer by particle interaction

Enhanced heat transfer by kinetic movement of boundary layer film by introducing particles with specialized surfaces. A boundary layer is stagnant, reducing heat transfer into a flowing fluid. Boundary layer heat transfer is primarily conduction. The introduction of specialized particles into fluid promotes boundary layer mixing, thereby converting conduction to convection through the film. Particles of the invention tumble while mixing the boundary layer, which provides low surface area energy sites around the particles. Kinetic movement increases nucleation formation for gas phase transfer during boiling. Metal and ceramic nanoparticles in fluids increase fluid thermal conductivity. By modifying surface characteristics of such nanoparticles to promote boundary layer mixing, fluid heat transfer and thermal conductivity will increase. Specialized surface characteristics of materials ensure that particles interface with the boundary layer to produce kinetic mixing and low surface area energy sites for accelerated nucleation, resulting in enhanced heat transfer of gas or liquid.
