Nanofluids have emerged as powerful instruments in heat transfer applications due to their improved thermophysical properties. Additionally, many equipments are started be operated within the range of transitional flow regions advances thermal management enhancement techniques. However, up date, friction factor and coefficient features nanofluids effect nanoparticle addition into base fluid on ...

The effects of a porous medium on the flow in the interface region between the porous wall and clear fluid are discussed. Laminar flows in the interface regions of foamed porous walls are microscopically simulated by the lattice Boltzmann method. The chosen porous structure is the body-centered-cubic or the unit cube structure whose porosity ranges . The velocity distribution in the interface r...

A structured Reynolds-averaged Navier–Stokes solver is directly coupled to a linear stability theory (LST) include the effect of laminar–turbulent transition in flow simulations. The flowfield variables are used both find streamlines along which can be predicted and provide LST code with required boundary-layer profiles. Instabilities included analysis Tollmien–Schlichting crossflow nature rele...

Direct numerical simulation was used to study laminar and turbulent flows in circular pipes with smoothly corrugated walls. The corrugation wavelength was kept constant at 0.419D, where D is the mean diameter of the wavy-wall pipe and the corrugation height was varied from zero to 0.08D. Flow rates were varied in steps between low values that generate laminar flow and higher values where the fl...
