This paper proposes an inexact Baugh-Wooley Wallace tree multiplier with novel architecture for 4:2 compressor optimised realisation using reversible logic. The proposed has ±1 Error Distance (ED) and 12.5% Rate (ER). efficacy of the logic based is measured in scales Gate Count (GC), Quantum Cost (QC), Garbage Output (GO) Ancilla Input (AI). able to reduce metrics GC, QC, GO AI by 50%, 15%, 25%...

Selection of each major type of Reciprocating, Rotary, Centrifugal and axial Compressor is briefly reviewed. It ls explained how the nondimensional scales of Specific Speed and Speclfic Diameter can be used to select any of the above configuration of Compression machinery at its optimum efficiency range. The paper presents the approach of Engineers Constructors in selecting compressors in petro...

Sanyo has originally introduced 6HP two-cylinder rotary compressors for packaged airconditioners in I 985. The concept of two-cylinder rotary compressor has been recently applied to room airconditioners(RACs) for the purpose of reducing vibration and noise of the unit. However. RACs are demanded to decrease the noise by lowering levels of the compressor noise. SanYo has newly developed the quie...

In a compressor the existence of the clearance volume is inevitable, even rolling piston compressor is a kind of compact structure compressor, overflow is a method to decrease the effect of clearance volume. In this paper, the overflow design on a rolling piston rotary compressor is discussed, which uses the high-pressure gas in the clearance volume, and discuss its effect on the performance of...

On the idealized situation of simply supported discharge tubes it is demonstrated how the discharge and suction pressures influence the resonance frequencies and thus the force transmission from the compressor to the compressor shell. The influence of flow velocity is also briefly discussed. With minor modifications, all results are also applicable to suction tubes in cases of high side compres...

The scroll compressor incorporates new construction concepts and is quite different from other types of compressor. This unique and simple compression mechanism has a number of advantages such as small size, light weight, high efficiency, long life, and quiet operation. The compliant mechanism is one of the key ways to improve the performance and reliability of scroll compressors. The concept o...

The complexity arising from the interactions between the pulsating flow, gas cavity and shell structure has been the major obstacle in realizing the prediction of the radiated sound level of heiiDetic compressors by a numerical simulation. In this work, a numerical procedure combining a computer simulation program of the compressor process and the Finite Element Method (FEM)/Boundary Element Me...

In this paper we investigate the behavior of higher order Galerkin expansions of the MooreGreitzer model of general transients in aeroengine compression systems. We assume steady state entrainment of the higher Fourier modes of the rotating stall cell which helps establish a framework for a simpli ed numerical analysis of the bifurcating solutions corresponding to rotating stall. For small valu...

In the Omega EP laser, the pulse must be stretched in time, amplified, and subsequently compressed in a grating compressor in order to obtain high peak power. A model was used to characterize the temporally resolved near-field and far-field beam distributions for several different compressor configurations that included grating alignment errors and grating surface figure errors. The spatio-temp...
