“…In parallel patterns, a certain interaction will not happen and can be ignored, whilst the interaction in non-parallel trends is important and should be considered. By using the SNRs listed in Table 5, the relationship between each of two variables is measured and presented in Figure 15 [34,35].…”

“…The superposition model sues SNRs, which are obtained from the Taguchi method, to estimate all possible ratios outside the orthogonal array. In this study, the superposition model (according to [35]) is used to predict the SNRs of all responses (4*4*4*4= 256). Considering the percentage of errors is close to zero and can be neglected [34], the superposition model for the four-level fourfactor problem will be:…”

“…By accomplishing only nine CFD tests, they improved the output of the vertical axis wind (VAW) turbine by 18%. Recently, Khanjanpour and Javadi [35], optimized the efficiency of a VAT turbine combining a mixed-level L18 (6 1 *3 3 ) Taguchi with 18 CFD simulations. They studied the effects of ratio of chord/radius, maximum camber, camber position, and twist angle on the performance of the VAT turbine.…”

“…The comprehensive evaluation index of an impeller of bent blade disc turbine was the highest. Khanjanpour 19 applied the Taguchi method to the optimization of the hydrodynamic characteristics of a vertical axis tidal turbine, the power coefficient of the optimized turbine increased by 24% compared with the baseline design, and the flow separation was greatly reduced. Wang 20 optimized the amplitude and wavelength of the serrations and twist angle of helical blade by the Taguchi method and found that the optimal parameter combination was an amplitude of 2.5% c b (blade chord length), a wavelength of c b /6, and blade twist angle of 60°.…”

The gas–solid fluidized bed is the key structure of industrial fluidization, and it is widely used in fields such as chemical reactors and industrial material conveying. To study the uniformity of velocity distribution ( Vu) in a fluidized bed and clarify the interaction mechanism between the geometric structure of the air chamber and the gas flow, in this paper, 16 novel chamber structures for powder unloading were designed based on the Taguchi method. Computational fluid dynamics was used to simulate the different chamber schemes, and the effects of various geometric factors on the response were analyzed based on the Taguchi method. The effect of the novel optimization model for powder unloading was verified by tests. The results show that the optimal combination of geometrical parameters is air chamber capacity ( V) at level 4, separation ratio ( K) at level 1 and clearance of splitter plate ( δ) at level 1, and δ has the greatest effect on the Vu1 and Vu2 in the fluidized bed. With the increase in δ and K, the velocity of the airflow away from the inlet side increases, and the area of the vortex near the splitter plate increases. Compared with the baseline model, the fluidized bed with the novel air chamber can effectively reduce the residual rate of powder unloading.

This scoping review assesses the current use of simulation-based design optimization (SBDO) in marine engineering, focusing on identifying research trends, methodologies, and application areas. Analyzing 277 studies from Scopus and Web of Science, the review finds that SBDO is predominantly applied to optimizing marine vessel hulls, including both surface and underwater types, and extends to key components like bows, sterns, propellers, and fins. It also covers marine structures and renewable energy systems. A notable trend is the preference for deterministic single-objective optimization methods, indicating potential growth areas in multi-objective and stochastic approaches. The review points out the necessity of integrating more comprehensive multidisciplinary optimization methods to address the complex challenges in marine environments. Despite the extensive application of SBDO in marine engineering, there remains a need for enhancing the methodologies’ efficiency and robustness. This review offers a critical overview of SBDO’s role in marine engineering and highlights opportunities for future research to advance the field.
