“…For each type of EC there is a special group of key dimensional parameters whose influence of errors on the stability of the characteristics is the most significant. Analysis of the key dimensional parameters of the EC installed in the car shows that the main linear dimension parameters, from the point of view of the effect on the stability of the characteristics, are the parameters forming the working air gap: the internal diameter of the stator and the outer diameter of the rotor [16].…”

A generalized quality criterion is proposed for the processes of designing and manufacturing electrical equipment. The relationship between the parameters of the technological process of manufacturing electrical equipment and the ones of statistical plans acceptance quality control is taking into account for the calculation of the criterion. This creates the prerequisites for effective management of design and manufacturing processes to achieve the desired level of quality.

“…The design loop for the impeller forming the optimization method based on GA analyzes the parameters of flow field, including pressure ratio, efficiency and Y+, as the inputs into the optimization code, to create new designs [25]. GA seeks to minimize or maximize the objective function as a combination of performance parameters of the compressor, including pressure ratio and efficiency.…”

It has always been important to study the development and improvement of the design of turbomachines, owing to the numerous uses of turbomachines and their high energy consumption. Accordingly, optimizing turbomachine performance is crucial for sustainable development. The design of impellers significantly affects the performance of centrifugal compressors. Numerous models and design methods proposed for this subject area, however, old and based on the 1D scheme. The present article developed a hybrid optimization model based on genetic algorithms (GA) and a 3D simulation of compressors to examine the certain parameters such as blade angle at leading and trailing edges and the starting point of splitter blades. New impeller design is proposed to optimize the base compressor. The contribution of this paper includes the automatic creation of generations for achieving the optimal design and designing splitter blades using a novel method. The present study concludes with presenting a new, more efficient, and stable design.

“…They didn't change the shape of blades. Neverov et al [19] used the NUMECA Fine/Turbo package with Spalart -Allmaras and Shear Stress Transport turbulence models, and investigated two radial impellers with a high-pressure at ψT = 0.71 and a low-pressure at ψT = 0.43. Shahram Derakhshan and Derakhshan investigated the slurry flow in centrifugal pumps to obtain an efficient optimization procedure.…”

The present paper seeks to model and simulate the function of a centrifugal GT4082 compressor and evaluates the effects of losses in the impeller, volute, and diffuser. It is also examined the mass parameter effect on the efficiency drop at different speeds. The total and static pressure drops are also examined in the volute and diffuser. Based on the experiments, the efficiency drops in these parts modeled at different mass parameters and speeds discovered to be maximized in the volute and diffuser at a specific speed. A global minimum was observed in the overall pressure drop and a global maximum in the static pressure drop versus a mass parameter.
