Structural reliability design of liquid oxygen supply pipeline based on fluid-solid-thermal coupling

Reliability - based Structural Design

Reliability based structural design

According to ISO 2394, structures shall be designed, constructed and maintained in such a way that they are suited for their use during the design working life in an economic way. To fulfil this requirement one needs insight into the risk and reliability under expected and non-expected actions. A key role in this respect is played by the structural reliability analysis (SRA). In this paper the ...

Research on Parametric Design of Hydraulic Retarder Based on Multi- Field Coupling of Heat, Fluid and Solid

In order to optimize the design method and improve the performance of hydraulic retarder, the numerical simulation of multi-field coupling of heat, fluid and solid is carried out to hydraulic retarder, based on the numerical computation and algorithm of heat-fluid coupling and fluid-solid coupling. The computation models of heat-fluid coupling and fluid-solid coupling of hydraulic retarder are ...

Oxygen contamination of the nitrous oxide pipeline supply.

Midogas (CIG Australia) nitrous oxide/oxygen blenders are commonly used in delivery wards in Australia. In this case report we describe an incident where a small hole in the diaphragm of the oxygen failure alarm in a Midogas nitrous oxide/oxygen blender led to retrograde flow of oxygen contaminating the nitrous oxide pipeline supply to the operating theatres and the delivery ward. This caused a...

Design of Reliability Insurance Scheme Based on Utility Function for Improvement of Distribution Grid Reliability

The regulatory schemes currently used for reliability improvement have weaknesses in the provision of quality services based on the customers’ perspective. These schemes consider the average of the service as a criterion to incentivize or penalize the distribution system operators (DSOs). On the other hand, most DSOs do not differentiate electricity services at the customer level, due to the st...
