Numerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel
Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

متن کاملTurbulent jet characteristics for axisymmetric and serrated nozzles
Turbulent jet large eddy simulations (LES) are performed at Mach 0.9 and Reynolds number around 10. Implicit large-eddy simulation (ILES) is employed, namely omitting explicit subgrid scale models. The Reynolds-averaged Navier-Stokes (RANS) solution is blended into the near wall region. This makes an overall hybrid LES-RANS approach. A Hamilton-Jacobi equation is applied to remove the disparate...

متن کاملNumerical Study of a Confined Axisymmetric Jet Impingement Heat Transfer with Nanofluids
A numerical simulation on confined impinging circular jet working with a mixture of water and Al2O3 nanoparticles is investigated. The flow is turbulent and a constant heat flux is applied on the heated plate. A two-phase mixture model approach has been adopted. Different nozzle-to-plate distance, nanoparticle volume concentrations and Reynolds number have been considered to study the thermal p...
