RANS Modeling of Turbulent Flow and Heat Transfer in a Droplet-Laden Mist Flow through a Ribbed Duct

چکیده

The local structure, turbulence, and heat transfer in a flat ribbed duct during the evaporation of water droplets gas flow were studied numerically using Eulerian approach. structure turbulent two-phase underwent significant changes comparison with without ribs. maximum value gas-phase turbulence was obtained region downstream rib, it almost twice as high kinetic energy between Finely dispersed small Stokes numbers penetrated well into separation observed over cross section; they could leave ribs due to their low inertia. Large inertial large present only mixing layer core, accumulated close wall towards rib. An addition evaporating caused enhancement (up 2.5 times) single-phase channel.

Effect of droplet interaction on droplet-laden turbulent channel flow

We present results of direct numerical simulation of heat transfer and droplet concentration in turbulent flow of a mixture of dry air, water vapor, and water droplets in a differentially heated channel. In particular, we study the effects of droplet collisions by comparing results of simulations with and without droplet collision model for several overall droplet volume fractions. The results ...

Heat Transfer from a Tube Bank in Cross Flow in a Duct

An experimental investigation on heat transfer coefficient is presented from three horizontal tubes in a vertical array in a duct for 500<ReD<6000. A mass transfer measuring technique based on psychrometry chart is used to determine heat transfer coefficient. The diameter of the tubes is 11 mm each spaced 40 mm apart and in-line pitch ratio varies &#10in the range 0.055<D/W<0.22. The experimen...

Large Eddy Simulation of Turbulent Flow and Heat Transfer in a Ribbed Coolant Passage

Numerical simulations of hydrodynamic and thermally fully developed turbulent flow are presented for flow through a stationary duct with periodic array of inline transverse rib turbulators. The rib height to hydraulic diameter ratio e/Dh is 0.1 and the rib pitch to rib height ratio P/e is 10. The effect of secondary flow due to presence of rib turbulators on heat and mass transfer has been inve...

Fluid flow and heat transfer characteristics in a curved rectangular duct using Al2O3-water nanofluid

In the present research, the laminar forced convective heat transfer and fluid flow characteristics for Al2O3-water nanofluid flowing in different bend (i.e., 180o and 90o) pipes have been investigated numerically in a three-dimensional computational domain using the finite volume technique. The effects of different pertinent parameters, such as the Reynolds number of the duct, volume fraction ...
