Thermal and economic analysis of preinsulated and twin-pipe heat network operation
Energy, 2020Abstract This study focuses on the economic analysis of the heating network modernization by using preinsulated pipes and twin-pipes. The cost analysis is based on different type, diameter, and technological diagrams of different heating network pipe variants (from DN25to DN100) and various types of insulation.

Effect of upstream developing length on the flow field of twin pipe jets
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2008It is well known that initial conditions significantly affect the flow field and the evolution characteristics of the jets. In the present study, experiments on twin pipe jets were performed to understand the effect of developing length on the twin-jet characteristics.

Free transverse vibrations of an elastically connected simply supported twin pipe system
Structural Engineering and Mechanics, 2010In this paper, free vibration analyses of a parallel placed twin pipe system simulated by simply supported-simply supported and fixed-fixed Euler-Bernoulli beams resting on Winkler elastic soil are presented. The motion of the system is described by a homogenous set of two partial differential equations, which is solved by a simulation method called ...

Applications and challenge of digital twin in life cycle of municipal pipe networks
Systems EngineeringAbstract Digital twin is the key technology to promote the life cycle digitalization and intelligent management of municipal pipe networks. To achieve intelligent closed‐loop management for the life cycle of municipal pipe networks, this paper first analyzed the meanings of “process‐oriented” and “object‐oriented” of digital twin and ...

Fracture Assessment of Austenitic Stainless Steel Piping With Twin Flaws in TIG Weld
Volume 1: Codes and Standards, 2009Fracture behavior of austenitic stainless steel piping for boiling water reactor (BWR) internals with circumferential through wall twin flaws at the weld was investigated. A 150A Sch.40 piping of type 316L stainless steel which has an outer diameter of 165.2 mm and a thickness of 7.1 mm was butt welded by tungsten inert gas (TIG) weld and single or ...
