In the present study, numerical simulations of drilling fluids that composed with two media on a mechanical agitator in a mud handling system were carried out to investigate the mixing performance of agitator and the keeping performance of homogeneity using both Eulerian and Lagrangian approaches. For simulation, two commercial softwares, STAR CCM+ based on Eulerian approach and Particleworks based...
In this paper, a novel heat sink with moving fins inserted between cooling fins is suggested for electronics cooling applications. In the novel heat sink, instead of the fan module, moving fins are inserted in the intervals of fixed fins (cooling fins) for generating fluid flow. By the relative motion of the moving fins to the cooling fins, heat dissipation from the cooling fins to the coolant and...
