“…Heat transfer and flow field characteristics have been investigated for the mixed convection case by many researchers [Boutina and Bessaih (2011);Lakhal et al (1997); Oztop (2010); Khodadadi (2006, 2007); ; Shaw et al (1987); Sourtiji et al (2011)]. Oztop and Dagtekin [2004] have numerically investigated the mixed convection in a vertical two-sided lid-driven differentially heated square enclosure.…”

In the present study, a novel approach based on Proper Orthogonal Decomposition (POD) and fuzzy clustering method is utilized to predict the flow field and heat transfer for the unsteady mixed convection in a square enclosure with two ventilation ports. An adiabatic thin fin is placed on the bottom wall of the cavity and all walls of the enclosure are kept at constant temperature. An oscillating velocity is imposed at the inlet port for a range of Strouhal numbers between 0.1 and 1. Reduced order models of the system are obtained with fuzzy-POD approach for Richardson number of 1 and 100. The estimation data set is obtained for Strouhal numbers 0.1 and 0.5, and the validation data set is obtained for Strouhal number of 0.25. A comparison of the modal coefficients obtained from the proposed approach compares well with the modal coefficients obtained by projecting the CFD data at Strouhal number of 0.25 onto the POD modes. The proposed approach is computationally efficient and the problem of numerical instability in the computation with the conventional Galerkin-POD approach can be circumvented.

“…Their results show that the increasing of the thermal conductivity and thickness of the porous matrix can decrease the maximum dimensionless temperature of the blocks and increases the mean Nusselt number. The laminar mixed convection air-cooling of two identical heat sources mounted in an inclined channel is studied numerically by Boutina and Bessaïh [22]. The correlations of average Nusselt numbers were obtained for different Reynolds numbers, inclination angle, dimension of heat sources, and the spacing between them.…”

Numerical investigation of the hydrodynamic amplification and thermal instabilities by imposing pulsation during forced convection of air cooling of nine identical heated blocks mounted on a horizontal channel is presented. The finite volume method has been used to solve the governing equations. The feature of this work is a narrowband of frequencies, where the enhancement of heat transfer of all electronic components is in the range of 25%-55% compared with steady nonpulsation flow is obtained. Good agreement between numerical simulations and experimental results available from the literature is obtained.
