In this article, modeling and optimization of power consumption of two–stage compressed air system has been investigated. To do so, the two – stage compressed air cycle with intercooler of FAJR Petroleum Company was considered. This cycle includes two centrifugal compressors, a shell, and a tube intercooler. For modeling of power consumption, actual compressors isentropic efficiencies and inter...

surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...
A compressor tip clearance flow control scheme is explored using fluidic actuators, the so-called " synthetic jets " , on the casing wall acting over the clearance region. The analysis of flow visualization images show the largest increase in mixing level when forced at the optimal frequency. A reduction in the tip clearance-related blockage is demonstrated using an array of synthetic jet actua...
We describe a tool for compressing XML data, with applications in data exchange and archiving, which usually achieves about twice the compression ratio of gzip at roughly the same speed. The compressor, called XMill, incorporates and combines existing compressors in order to apply them to heterogeneous XML data: it uses zlib, the library function for gzip, a collection of datatype speciic compr...
Received Apr 24, 2016 Revised Aug 3, 2016 Accepted Aug 18, 2016 In this paper, a 8x8 multiplier is realized by using 4-2 and 5-2 compressors. Low-power high speed 4-2 compressors and 5-2 compressors are extensively utilized for numerical realizations. Both the compressors circuits that is the 4-2 compressor circuit and 5-2 compressor circuit internally consist of the logic gates i.e. the XOR an...
Design optimization of transonic airfoils for rotary blades is a challenging subject that remarkably affects the stage and overall performance axial-flow compressors. This paper describes surrogate-based multi-objective process over blade. blade works in first high-pressure pre-designed industrial axial compressor. It experiences massive separation behind an impinging shock wave its suction sid...
