“…A latin hypercube design was employed to obtain the sets of sampling points and the NSGA-II method was used to determine the optimal design from the Kriging response surface. Zhou et al [9] observed a good agreement between the predicted values by the Kriging model and the CFD with an average relative error of 2.74% and 2.61% for the efficiency and flowrate, respectively. Furthermore, the optimal design improved the efficiency by 4.21% compared to the initial design.…”

“…Any validation of the obtained optimum design by a metamodel was accomplished by CFD or experimental tests. In a recent study by Zhou et al [9], the Kriging surrogate model was coupled with CFD to optimize the blade profile for a centrifugal SCF. The authors used the modified Hicks-Henne function to design a simple arc blade, where three amplitude coefficients were selected as input parameters for the optimization process.…”

The restrictions related to air quality are increasing making the improvement of the air system important. The squirrel cage fan (SCF), also known as forward-curved multiblade centrifugal fan, is widely used in vacuum systems. Most of researches so far used commercial software to study and optimize the SCF. In the present study, a complete automatic optimization process loop is developed based only on open source libraries: Dakota, Salome and OpenFOAM. Up to seven design parameters are selected. The Latin Hypercube Sampling (LHS) method is preferred to determine the design points and then the Kriging and Efficient Global optimization (EGO) metamodels are built. A 3D incompressible simple FOAM solver is coupled to the Multiple reference frame (MRF) approach to model the flow in the SCF. An efficiency improvement of 8.46% is reached by the EGO approach. A strong vortex is observed in the cutoff region. The optimal design is finally validated against the produced prototype, with an error of 3.4% on the efficiency.

The primary air fan functions as a primary air producer which is used as air to transport coal powder from the pulverizer to the burner to be burned in the boiler furnace. This study aims to obtain the effect of the rotation variation of fan to fluid flow characteristics such as the distribution of total pressure, the dynamic pressure, the pressure static contours, velocity distribution, and the fan optimal efficiency. This study was numerical study with simulated a backward impeller type centrifugal fan in a two-dimension model using Fluid Computational software with the multiple reference frame method with the variation of fan rotation. Based on the visualization of the pressure contour and velocity distribution, it could be concluded that there was a volute phenomenon, this was indicated that the greater the volume area in the volute is the greater the total pressure value too. Based on the visualization of the outlet velocity distribution at the position of -0,8531m to -1,01301m, it was found that the velocity is close to the value of 0 m/s2. It showed that the minimum velocity in the area due to the volute tongue radius occurs a flow collision and it impacted the velocity in the area decreased up to V=0. From the simulation results, it was found that the greater the fan rotation value was the greater the efficiency value too. It would be verified by the actual operating data of the centrifugal fan with a minimum rotation range value of 1194 rpm to a maximum of 1468 rpm

“…Della Vecchia et al (2014) used Parsec for parameterized characterization of an airfoil, combined with genetic algorithms (GAs) for optimization design, and thus obtained a winged type with good aerodynamic performance. Zhou et al (2021) used Hicks-Henne bump functions to conduct parameterized characterization of the blades of a multi-blade centrifugal fan and combined the Kriging approximate model and NSGA-II to conduct multi-objective optimization design of the blades. After optimization, the aerodynamic performance of the blades has been significantly improved.…”

As one of the key components of the heat pump system, compared to that of a conventional axial fan, the blade tip area of a forward-swept axial fan is much larger than its blade root, which is the main noise source of the fan and also has an important influence on the fan efficiency. Enhancement of the aerodynamic performance and efficiency of a forward-swept axial fan was addressed by utilizing the Bezier function to parameterize the forward-swept curve on blade tops. In order to quickly select an agent model suitable for the project, an ES model was established by integration of the radial basis function model and the Kriging model. When NSGA-II was combined, multi-objective optimization was carried out with the flow rate and total pressure efficiency as optimization goals. Analysis of optimization results revealed that the optimized axial flow fan’s flow rate and total pressure efficiency were improved to some degree. At the design working point, the fan’s flow rate increased by 1.78 m³/min, while the total pressure efficiency increased by 3.0%. These results lay solid foundation for energy saving of the heat pump system.
