The governing equations based on the SST k-w model used to describe the turbulence, are solved by the final volume approach using the SIMPLE algorithm. The velocity and temperature fields, the temperature profiles, as well as the Nusselt number distribution were presented for a typical case.

Numerical study of heat transfer and fluid flow in a channel with staggered arc-shaped baffles / Younes Menni in COST, N° 18 ([01/01/2017])

Public ISBD [article]  in COST > N° 18 [01/01/2017] . - p. 41 Titre : Numerical study of heat transfer and fluid flow in a channel with staggered arc-shaped baffles Type de document : texte imprimé Auteurs : Younes Menni, Auteur ; Ahmed Azzi, Auteur ; Chafika Zidani, Auteur Année de publication : 2017 Article en page(s) : p. 41 Langues : Anglais Mots-clés : Arc-shaped baffle  CFD  heat transfer  rectangular channel Résumé : A numerical study has been carried out to examine steady turbulent flow and heat transfer characteristics in a two-dimensional isothermal wall rectangular channel with staggered 30° arc-shaped baffles. The air flow rate is in terms of Reynolds numbers based on the inlet hydraulic diameter of the test channel ranging from 4,000 to 16,000. The CFD software FLUENT6.3 was used to simulate the flow and heat transfer. The simulations focused on the influence of Reynolds number and arc-baffle height on heat transfer and pressure drop measurements. The results reveal essentially, that the airflow is characterized by strong deformations and large recirculation regions. In general, the rise in the Reynolds number results in the increase in the Nusselt number and friction factor values. Also, for a constant value of the Reynolds number, an increase in the arc-baffle height causes a substantial increase in the Nusselt number but the friction loss is also verysignificant.

Numerical study of turbulent heat transfer in a trapezoial channel with flat bafeles / Younes Menni in COST, N° 17 ([01/07/2016])

The fluid is considered, Newtonian, incompressible with constant properties. The CFD software FLUENT 6.3 is used to simulate the fluid flow and heat transfer fields. The governing equations, based on the SST k-w model used to describe the turbulence, are discretized using the finite volume approach. The numerical results were compared with available experimental data from the literature and good agreement is obtained.
