According to the cylindrical coordinate system, the three-dimensional liquid flow in special chemical stirred kettle can be divided into axial flow, radial flow and circumferential flow (or tangential flow).
In the turbulent state, the impeller not only produces circular flow, but also produces a lot of axial flow, which is a typical axial flow impeller. In addition to the circumferential flow generated by the liquid rotating with the impeller, the centrifugal force of the impeller also causes the liquid to shoot along the blade towards the groove wall, forming a strong radial flow. Therefore, these impellers are called radial flow impellers. Curved blade turbines have more axial flow components than straight blade disk turbines, so they are often used in situations where more axial flow is required.
The spiral belt impeller and spiral impeller make the high viscosity liquid flow axially; The anchoring impeller mainly produces the circumferential flow of liquid.
CFD simulation has been able to obtain the details of the internal flow field of turbo machinery within the range of engineering accuracy, and can also truly reflect complex internal flow phenomena, and even predict new phenomena that have not been found in theoretical analysis and experimental research. The CFD method is used to test the performance of the Shengkier prototype, and can well predict the mechanical properties of the fluid and internal flow eddy current, secondary flow, boundary layer separation, drafting, and blade flutter phenomenon in the drawing design stage, so as to strive to have hidden trouble in the design stage, to a certain extent, replace the test, in order to reduce the cost and shorten the development cycle. Shunkel uses CFD simulation technology to better design the impeller to meet the maximum fluid requirements. The main recommended Shengkair impeller is as follows:
The R763 gas dispersion impeller uses a unique blade design to push a larger volume of fluid, reducing system resistance and enabling more consistent power uptake.
