According to recent research from the United States, "Drag reduction in heavy oil transport systems is a key for high-efficiency oil transfer and, thus, for energy conservation. fit this paper, we investigated the influence of viscosity, velocity, and velocity-gradient fields on drag resistance in fluid flow with variable viscosity in terms of the field synergy. The theoretical analysis indicates that the drag during varying viscosity fluid flow processes depends upon not only the synergy between the, velocity and its gradient over the entire flow domain but also the viscosity and velocity gradient,it the boundary, That is, for a given now rate or inlet velocity, ...
