Development of New Multipurpose Transformable Multiple Impeller (Advanced Mixing Impeller) for Highly Viscous Fluids

Laminar mixing performance of high viscous fluid is influenced by the shape of the mixing impeller. The axial flow in the mixing vessel was the most important flow under the laminar that Reynolds number was less than 10. The most popular impeller which generates the axial flow is a helical ribbon impeller, but the production cost is high because of the complicated shape. By combining of some simple pitched blade impellers, authors developed a new type impeller that the production cost is lower than that of the helical ribbon impeller. As a result, the new impeller had the same mixing performance as a helical ribbon impeller.
