This paper presents an optimization design method for centrifugal compressors based on one-dimensional calculations and analyses. It consists of two parts: (1) centrifugal compressor geometry optimization based on one-dimensional calculations and (2) matching optimization of the vaned diffuser with an impeller based on the required throat area. A low pressure stage centrifugal compressor in a M...

Abstract In recent years, evolutionary algorithms have shown great advantages in the field of feature selection because their simplicity and potential global search capability. However, most existing based on computation are wrapper methods, which computationally expensive, especially for high-dimensional biomedical data. To significantly reduce computational cost, it is essential to study an e...

Designing a supply chain to comply with environmental policy requires awareness of how work and/or production methods impact the environment and what needs be done reduce those impacts make company more sustainable. This is dynamic process that occurs at both strategic operational levels. However, being environmentally friendly does not necessarily mean improving efficiency system same time. Th...

Multistage refrigeration system plays a vital role in industrial for the chemical, petrochemical, pharmaceuticals and food industries. Modern chemical industries are complex, problems commonly multi-dimensional, non-linear time-consuming. This study presents application of evolutionary computation techniques, namely PSO (particle swarm optimization), GA (Genetic Algorithm) SA (Simulated Anneali...
