متن کاملLarge-eddy simulation of the flow in a low-speed centrifugal compressor
The results of a series of numerical simulations for the NASA low-speed centrifugal compressor are presented. Large-eddy simulation (LES) is carried out together with the most commonly used Reynoldsaveraged Navier–Stokes (RANS) models, including the mixing length, k– and k– models. Predictions are compared with the available experimental data. It is seen that quantitative predictions of LES are...
متن کاملDesign, Analysis and Fabrication of a Meso-scale Centrifugal Compressor
A gas or vapor compressor is one of the key components of many engineering systems, such as certain designs of vapor compression refrigeration systems, cryo-coolers, air handlers. For meso-scale systems with linear dimensions of a few centimeters, conventional designs do not work efficiently because of rather large relative tolerances, and hence these meso-scale systems require micro-fabricated...
متن کاملCFD Analysis of Off-design Centrifugal Compressor Operation and Performance
This paper presents some of the results from a Master’s thesis research into the performance and operation of a centrifugal compressor at off-design operating conditions using advanced computational fluid dynamics (CFD) techniques. ANSYS CFX is the CFD solver used in this blind study to evaluate the ability of modern CFD software to predict the performance of centrifugal compressors operating a...
متن کاملOptimal Design of a Centrifugal Compressor Impeller Using Evolutionary Algorithms
An optimization study was conducted on a centrifugal compressor. Eight design variables were chosen from the control points for the Bezier curves which widely influenced the geometric variation; four design variables were selected to optimize the flow passage between the hub and the shroud, and other four design variables were used to improve the performance of the impeller blade. As an optimiz...
