Seyyedi, S. M.; Ganji, D. D.; Gorji, M.; Bararnia, H.; Soleimani, S. Forced convection heat transfer due to different inclination angles of splitter behind square cylinder. (English) Zbl 1376.76062 Appl. Math. Mech., Engl. Ed. 34, No. 5, 541-558 (2013). Summary: A numerical investigation is carried out to study the effect of splitter’s inclination angle behind an inclined square cylinder on the forced convection heat transfer in a plan channel using the lattice Boltzmann method (LBM). The simulations are conducted for the pertinent parameters in the following ranges: the Reynolds number Re=50–300, the gap ratio \(G/d = 2\), and the splitter’s inclination angle \(\theta = 0^\circ-90^\circ\). The results show that with the increase in the angle of the splitter, the drag coefficient initially decreases and then increases. Moreover, the time-averaged Nusselt number at a certain angle increases noticeably.
