Compressed Gas Safety for Experimental Fusion Facilities

Safety distance between underground natural gas and water pipeline facilities

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper pr...

Compressed natural gas bus safety: a quantitative risk assessment.

This study assesses the fire safety risks associated with compressed natural gas (CNG) vehicle systems, comprising primarily a typical school bus and supporting fuel infrastructure. The study determines the sensitivity of the results to variations in component failure rates and consequences of fire events. The components and subsystems that contribute most to fire safety risk are determined. Fi...

Lessons learnt from ITER safety & licensing for DEMO and future nuclear fusion facilities

Experimental Facilities and Modelling for Rarefied Aerodynamics

The present lecture is devoted to experimental and theoretical modelling for rarefied aerodynamics. General features of experimental studies in rarefied flows are discussed. Experimental facilities designed in Saint Petersburg State University for rarefied aerodynamics and plasma flow control are described. Several theoretical models for non-equilibrium reacting flows in the slip regime are pre...

Optimization of energy consumption and offering a procedure for cooling gas compression facilities at gas compression stations

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 ...
