MANFIS–GA Heat Transfer Analysis and Optimization of Fins with Elliptical Perforation

Thermal Performance Optimization of Perforated Fins for Flat Plate Heat Sinks Using CFD Approach

“…Equal initial surface temperatures were set for all the HS surfaces to be at 300 K. The initial calculation pressure and temperature were set to be similar to the enclosure initial conditions (To=298 K and Po=101.325 kPa) while the airflow was set at a static condition (0.0 m/sec) inside the enclosure and near the fins' surfaces, as shown in Table 2. This is because selecting these options to make the numerical calculations more stable, and the results are closer to the real-time outcomes [25]. The bottom side of the model (heat sink base) was set up to be a fixed wall, and five supplied heat fluxes were used.…”

“…The entire flow of the air through the perforations and near the wall of the HS fins was assumed as a turbulent flow. Therefore, Re-Normalisation Group k-epsilon (RNG k-ε) turbulence model was used to numerically investigate and analyse the turbulence flow inside the enclosure [25]. It is worth to be mentioned that the Boussinesq approximation was used for the proposed model to simulate the buoyancy effect of the moving air caused by the density variation throughout the convection heat transfer.…”

“…There exists an algorithm proposed by Balachandar et al [23] that targets optimized design for superior thermal performance. This algorithm is accompanied by a validated computational fluid dynamics (CFD) model, which is employed to numerically analyze the impact of elliptical perforations on the heat dissipation rate of solid fins within the utilized heat sink (HS) relative to the surrounding environment.…”
