A Numerical Study on Non-Isothermal Flow Through a Rotating Curved Duct with Square Cross Section
Abstract: Non-isothermal flow through a rotating curved duct with square cross section is studied numerically by using the spectral method, and covering a wide range of the Taylor number, Tr, 2000 0 Tr and Dean number, , Dn 0Dn 2000. A temperature difference is applied across the vertical sidewalls for Grashof number Gr = 500, where the outer wall is heated and the inner one cooled. The r...
متن کاملSteady and Unsteady Solutions of Non-Isothermal Turbulent Flow through a Curved Duct with Square Cross Section
In this paper, a comprehensive numerical study is presented for the fully developed two-dimensional flow of viscous incompressible fluid through a curved duct with square cross section. Numerical calculations are carried out over a wide range of the Dean number 6500 100 Dn for the curvature 5 . 0 . A temperature difference is applied across the vertical sidewalls for the Grashof number ...
متن کاملSteady Flow in a Curved Pipe with Circular Cross-Section. Comparison of Numerical and Experimental Results
Numerical solution has been obtained of the equations of motion of a viscous incompressible fluid in a curved annular conduit with circular cross-section. These equations are approximated by finite-difference equations which are of the second-order accuracy with respect to the grid sizes. The computed results are presented for the range 96 D 8000 , where D is the Dean number of the flow and for...
متن کاملFluid 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 ...
متن کاملHeat transfer in MHD square duct flow of nanofluid with discrete heat sources
The effect of thermal and solutal buoyancy induced by a discrete source of heat and mass transfer in a square duct under the influence of magnetic field, especially at the turbulent regime for the first time is reported. Al2O3/water nanofluid is used with constant heat flux from three discrete heat sources. In the present study, the effects of Reynolds number (100 to 3000), particle volume frac...
