This paper presents 16×16 bit Radix-4 Modified Booth’s Multiplier (MBM) optimized for high speed multiplication by using pipeline Technique. This paper aims at reduction of hardware utilization. This is accomplished by the use of 3:2 compressor adders. An efficient VHDL code has been written, successfully simulated on Modelsim 10.2 simulator and Xilinx 12.4 navigator is used for synthesizing th...

An air compressor is the core component of supply system a hydrogen fuel cell, which demands high efficiency and reliable stability in wide operation region. In this work, centrifugal for cell first designed then measured experimentally. Furthermore, test rig assessing aerodynamic performance established, includes pipeline, gas flowmeter, flow regulating valve, pressure transmitter, compressor,...

In this paper, a glycol defrosting system using waste heat exhaust from refrigeration compressor is designed. The numerical model, transfer model and frost growth were established. thickness, consumption ethylene flow rate calculated, the pipeline was project solves problems of traditional cold storage, such as high power consumption, fluctuation storage temperature, hidden danger safety, conde...

As gas pipeline systems become larger and more complex, the importance of optimally operating planning these facilities has increased. The capital costs expenses are so large that even small improvements in use system can involve sums money. Purpose. This article proposes a method to improve reliability optimization power supply for compressor stations. novelty proposed work is development new ...

Abstract In this paper, we describe an algorithmic framework for the optimal operation of transient gas transport networks consisting a hierarchical MILP formulation together with sequential linear programming inspired post-processing routine. Its implementation is part KOMPASS decision support system, which currently used in industrial setting. Real-world are controlled by operating complex pi...
