Numerical investigation of entropy generation and heat transfer of pulsating flow in a horizontal channel with an open cavity

引用

Journal of Hydrodynamics 2017年第4期29卷 632-646页

作者： fatma Zamzari Zouhaier mehrez Afif el Cafsi Ali Belghith Patrick Le Quéré Faculty of Sciences of Tunis Laboratory of Energy Heat and Mass Transfer (LETTM) Department of Physics El Manar University Computer Science Laboratory for mechanics and Engineering Sciences (LImSI)

In this study, the entropy generation and the heat transfer of pulsating air flow in a horizontal channel with an open cavity heated from below with uniform temperature distribution are numerically investigated. A numerical method based on finite volume method is used to discretize the governing equations. At the inlet of the channel, pulsating velocity is imposed for a range of Strouhal numbers Stpfrom 0 to 1 and amplitude Apfrom 0 to 0.5. The effects of the governing parameters, such as frequency and amplitude of the pulsation, Richardson number, Ri, and aspect ratio of the cavity, L/H, on the flow field, temperature distribution, average Nusselt number and average entropy generation, are numerically analyzed. The results indicate that the heat transfer and entropy generation are strongly affected by the frequency and amplitude of the pulsation and this depends on the Richardson number and aspect ratio of the cavity. The pulsation is more effective with the aspect ratio of the cavity L/H= 1.5 in terms of heat transfer enhancement and entropy generation minimization.
