Numerical simulation of the oscillating thin plate impact on nanofluids flow in channel
The present numerical study aims to present the effect of using a titled oscillating thin plate with different angles of inclination on the Al2O3-water nanofluid flow and heat transfer performance. The subsequent work establishes methods for forming fluid-structure interactions by impact of Al2O3-water nanofluid at 0.1-1.0 vol. % volume fraction upon the thin plate using COMSOL Multiphysics 5.4. The turbulent model is solved using the (k-?) model and the assembly of the flow around the thin plate obstacle has been confirmed at Reynolds number of Re=4?104. It exemplifies how Nanofluid flow interaction can distort structures. The current study donates to the study of the turbulent, two-dimensional, stationary and incompressible flow around an oscillating thin plate that has inclined angles with upstream and downstream that mounted inside a horizontal channel. The numerical study includes investigation the effect of five inclination angles of the thin plate as (30, 60, 90, 120 and 150?) on the pressure, velocity, and temperatures contours of the Al2O3-water nanofluid. Also, the study presented the profile of the drag and left force of the thin plate that causing by the fluid flow. The results showed that the occurrence of a titled oscillating thin plate inside the flow direction leads to an increase pressure drop, von mises deformation stress, x-displacement and drag force fields and the Nusselt number. Where the pressure increased from 2.61?103 to 6.21?103 pa, the von mises stress increased from 4.43?106 to 1.78?107 N/m, and the X-displacement increased from 1.6 to 5.5 mm when increasing the plate angle from 30 to 90?.
