Özet
In this study, the forced convection properties of teardrop-shaped dimpled fins, Fe3O4/H2O ferrofluid, and constant magnetic field parameters were investigated numerically and experimentally. The study consists of two parts. In the first part, a numerical simulation was conducted, incorporating all relevant parameters, and the results were analyzed. In the second part, the experimental setup was completed for the scenario that yields the highest performance evaluation criterion value, as determined from the numerical results. The Reynolds number (10000≤Re ≤ 50000), the size of the teardrop-shaped dimple (BTD, MTD and STD), dimples distance (30≤P ≤ 50), constant heat flux (qʺ = 20 kW/m2), ferrofluid concentration ratio (0.0≤φvol.≤2.0) and the constant magnetic field strength applied at x/D = 20 location (0 T ≤ B0 ≤ 0.3 T) were studied experimentally and numerically. The findings showed that the DT9 …
