In the present paper, the regimes of flow and mixing of water and a nanofluid with aluminum oxide nanoparticles in a T-shaped microchannel have been studied numerically. The Reynolds number was varied from 10 to 400, and the volume concentration of nanoparticles was varied from 0 to 10%. Nanofluids with mean sizes of particles from 50 to 150 nm were considered. The viscosity coefficient of the nanofluid...
A numerical method is used to compute the unsteady transverse jets flow and study the air-fuel mixing characteristics in the unsteady flowfield. The unsteady compressible Navier-Stokes equations are solved using a high-order AUSM+ method with dual-time-step implicit time scheme. It is found that the transverse jets flowfield is very unsteady and the unsteadiness is caused by the primary vortices emanating...
In this paper, ANSYS POLYFLOW with finite element-based was adopted for the three-dimensional flow-field simulation in the rubber mixing process, and integrated with the methods including overlapping grid, Picard iteration and time-stepping scheme. The viscosity field cloud-picture in cycle process of rubber-mixing was obtained, and then the mixing-field characteristics under different process parameters...
