Performance-critical pipelines—such as a packet processing pipeline in a network device—are built from a sequence of simple processing modules, connected by FIFOs. Due to their complex sequential behavior, the worst case throughput, as well as the size of the interconnecting FIFOs, are currently designed using very rough heuristics. Such systems are usually validated by simulation, or worse, fi...

A novel VLSI pipeline architecture for high-speed clockless computation is proposed. It features gate-level pipelining to maximize throughput and uses dynamic latches to keep the latency low. The most salient property is the asynchronous operation using a modi ed handshake protocol. Data words are accompanied by associated control signals resembling a local clock and propagate in coherent waves...

The pipelines in mountainous areas have complex terrain conditions and pass through many densely populated areas. Once a pipeline leakage accident occurs, it will cause serious damage to the surrounding people environment. In this article, diffusion model of bare natural gas is established for exposed scenario, simulation scheme according characteristics pipeline-laying processes environmental ...

As an important working condition in water conveyance projects, the filling process of pipelines is a complex hydraulic transition involving water–air two-phase flow with sharp pressure changes that can easily cause pipeline damage. In light during filling, this study explores right-angle elbow using CFD numerical simulations and physical model experiments, analyzing phase volume fraction, wate...

Rapid depletion of energy resources has immensely affected the transportation sector, where the cargo transportation prices are rising considerably each year. Efforts have been made to develop newer modes of cargo transportation worldwide that are both economical and efficient for a long time. One such mode is the use of energy contained within fluids that flows in the pipelines for transportat...

One of the most important methods of transporting natural gas in Iran and other parts of the world is the utilization of a network of pipelines. Compression station and turbo compressor units play an important role in gas supply through pipelines. One of the primary concerns in these units is the reduction of fuel consumption. By cooling of exhaust gas from the source station, the pressure ...
