description The present work investigates the influence of baffle configuration and flow parameters on the heat transfer and entropy generation of a baffled channel used to cool a hot surface. A numerical simulation and optimization per the Taguchi analysis were performed. Reynolds numbers (Re) from 5000 to 15000 were investigated, baffle angles (β) from 60 to 90° were investigated, and the insertion ratio (C/H) ranged from 0.525 to 0.625. The optimization results with the highest cooling target yielded optimum values of Re = 15000, β = 90°, and C/H = 0.625, with a maximum Nusselt number of 191.3. With this configuration, the dimensionless entropy generation was a minimum of Sm = 3.302. The highest thermo-hydraulic performance was 1.028 with the optimum configuration of Re = 5000, β = 90°, and C/H = 0.525. The Reynolds number has the highest influence on the Nusselt number, thermo-hydraulic performance, and dimensionless entropy generation. The baffle angle has the lowest effect on the Nusselt number and entropy generation, while the insertion ratio has the lowest effect on the thermo-hydraulic performance.
