Abstract
A computational fluid dynamics model is used for the simulation of laminar flow of water–Al_{2}O_{3} nanofluid in a confined slot impinging jet. The (steady-state and two-dimensional) Eulerian–Lagrangian model is used considering fluid–particle and particle–wall interactions (i.e., two-way coupling). A collocated grid and the SIMPLE algorithm are used for the coupling of pressure and velocity fields. The deposition model is used to investigate the effect of particle deposition on the impingement surface. Results indicate that the particle trajectory becomes stable farther from the jet with a rising Reynolds number and jet-impingement surface distance ratio. The heat transfer coefficient of the mixture model is higher than that of the Eulerian–Lagrangian model.
