![]() ![]() Mixing is performed to allow heat and/or mass transfer to occur between one or more streams, components or phases. Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration). The pump of claim 13, wherein said means for connecting said first discoidal member and said second discoidal member comprises a plurality of adjustable rods connected to a periphery of said first discoidal member and to a periphery of said second discoidal member.In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous. This is known as the dead zone, and dead zones create significant barriers to pumping efficiency in disc pumps.ġ4. HVF speed decreases the further away it is from the disc surface until it reaches a distance where the HVF is stagnant. ![]() HVF speed is greatest next to the boundary where the surface of the disc meets the HVF. This is because disc pumps rely on boundary layer theory as the pumping mechanism, which means that HVFs are pumped by the movement created by friction between the surface of the disc and the HVFs. Regardless of the existence of vanes on the disc impeller, dead zones are created at a certain distance away from the disc and slippage occurs at the surface of the disc. Alternatively, a disc impeller can be provided with no channels or vanes. ![]() Disc impeller can be provided with vanes or channels for imparting the necessary centrifugal force on HVFs. Disc impellers are impellers shaped like a disc that rotate in the fluid so as to impart motion on the fluid.
