Turbulence Combined Convective Heat Transfer and Nanofluids Flows over Double Forward Facing Steps

Enhancement of Heat Transfer over a Double Forward Facing Step with Square Obstacle through Taguchi’s Optimization Technique

In this paper, the heat transfer to the fluid, passing through the double forward facing step (FFS) channel with square obstacle is enhanced by Taguchi’s S/N ratio analysis. Flow through the forward facing step channel has a wide range of applications in thermal systems due to its flow separation and subsequent reattachment, which in turn enhances the heat transfer. Flow separation and reattach...

Convective Heat Transfer of Nanofluids Flows Through an Isothermally Heated Curved Pipe

Heat Transfer and Turbulent Fluid Flow over Vertical Double Forward-Facing Step

Numerical study of heat transfer and fluid flow over vertical double forward facing step were presented. The k-w model with finite volume method was employed to solve continuity, momentum, and energy equations. Different step heights were adopted for range of Reynolds number varied from 10000 to 40000, and range of temperature varied from 310K to 340 K. The straight side of duct is insulated wh...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...

Application of nanofluids for heat transfer enhancement of separated flows encountered in a backward facing step

Numerical investigation of heat transfer over a backward facing step (BFS), using nanofluids is presented. Different volume fractions of nanoparticles are presented in the base fluid besides different type of nanoparticles have been used. The finite volume technique is used to solve the momentum and energy equations. The distribution of Nusselt number at the top and the bottom walls of the BFS ...
