TLDR
In this paper, numerical analysis was performed to investigate thermal fluid-flow transport phenomena in channel under asymmetrical heat flux from both side walls, where emphasis was placed on the effect of heat-flux ratio from both sides on the velocity and thermal fields.Abstract:
Numerical analysis is performed to investigate thermal fluid-flow transport phenomena in channel under asymmetrical heat flux from both side walls. Emphasis is placed on an effect of heat-flux ratio from both sides on the velocity and thermal fields. The low-Reynolds-number κ-e turbulence model and the two-equation heat-transfer model are employed to determine turbulent viscosity and thermal eddy diffusivity, respectivelyread more

Numerical development of heat transfer correlation in asymmetrically heated turbulent channel flow
TL;DR: In this article, a new correlation for symmetrically and asymmetrically heated channels associated with a turbulent flow is developed using Large Eddy Simulations, which involves a specific term to handle asymmetric conditions.

Asymmetric reverse transition phenomenon in internal turbulent channel flows due to temperature gradients
TL;DR: In this paper, the reverse transition of turbulent Poiseuille flows is investigated in the presence of a strong transverse temperature gradient in the wall layer that has to be modeled by a Reynolds-averaged Navier-Stokes (RANS) model.

Numerical study of turbulent flow in asymmetrically heated horizontal channel
TL;DR: In this article, a low Reynolds number turbulent flow of Helium in a horizontal channel subjected to asymmetric heating was studied using a low-Reynolds number turbulence model, and the results from the study were used to obtain laminarization criterion as a function of inlet Reynolds number, non-dimensional wall heat flux, and ratio of top wall heat flow to bottom wall flux.

Transition from the Chaotic Turbulence to the Turbulent Structures
TL;DR: In this paper, strong plasma turbulence may be constructed of discrete formations, viz., Langmuir solitons, and the relay race model provides the proper direction of the energetic flux over scales from the source towards the leakage.

A Two-Equation Model for Heat Transport in Wall Turbulent Shear Flows
Yasutaka Nagano,C. Kim +1 more
TL;DR: In this article, a two-equation level turbulence model is proposed for closed the energy equation, which does not require questionable assumptions for the turbulent Prandtl number, and is tested on a flat-plate boundary layer and the thermal entrance region of a pipe.
