TLDR
In this paper, the effect of step height on turbulent mixed convection flow along a vertical flat plate was examined for step heights of 0, 11, and 22 mm at a free stream air velocity, u ∞, of 0.55 m⋅s−1, and a temperature difference, ΔT, of 30 ǫ°C between the heated walls and the free flow air (corresponding to a local Grashof number Gr x i = 6.45 × 10 10 ).About:

Effect of a rotating cylinder in forced convection of ferrofluid over a backward facing step
TL;DR: In this article, the effects of magnetic dipole strength and cylinder rotation angle on heat transfer enhancement and fluid flow characteristics of a rotating cylinder under the influence of the magnetic dipoles in backward facing step geometry were analyzed.
Journal ArticleDOI
A review of Backward-Facing Step (BFS) flow mechanisms, heat transfer and control
TL;DR: It is shown that the step size (duct expansion ratio) will define the basic re-circulation and re-attachment process, while the coupled effects of inflow parameters and the perturbation designs also help shape the flow behaviors after BFS.

TL;DR: Nanofluids are solid/liquid suspensions of higher thermal conductivity and viscosity compared to common working fluids as mentioned in this paper, and their application in heat transfer enhancement is prospective. But their performance is limited.

A new turbulence model for predicting fluid flow and heat transfer in separating and reattaching flows—I. Flow field calculations
TL;DR: In this paper, the Kolmogorov velocity scale was introduced to account for the near-wall and low-Reynolds-number effects in both attached and detached flows.

Combined Heat Transfer and Fluid Dynamic Measurements Downstream of a Backward-Facing Step
J. C. Vogel,John K. Eaton +1 more
TL;DR: In this paper, the authors combined heat transfer and fluid dynamic measurements in a separated and reattaching boundary layer, with emphasis on the near-wall region, to obtain Stanton number profiles as a function of Reynolds number and boundary layer thickness at separation.

Turbulence measurements in a natural convection boundary layer along a vertical flat plate
Toshihiro Tsuji,Yasutaka Nagano +1 more
TL;DR: In this article, the reliability of Reynolds stress and turbulent heat flux measurements is verified by the excellent agreement with the indirect measurements estimated by integrating momentum and thermal energy equations with measured mean velocity and mean temperature.
