Numerical simulation of high-temperature creep deformation in Zr-2.5%Nb pressure tubes of CANDU reactors
(Elsevier, 2020-01)
The present paper deals with the development of a numerical approach to predict thermal creep in pressure tubes of CANDU nuclear power reactors. This phenomenon plays a crucial role under accident conditions, where the ...
Transferred plasma jet as a tool to improve the wettability of inner surfaces of polymer tubes
(Taylor & Francis Ltd, 2017-01-01)
The wettability of the inner surfaces of vinyl, polyurethane, and silicone tubes was modified using an atmospheric pressure plasma jet operated in argon. A specific plasma jet configuration, transferred plasma jet, developed ...
Pressure drop correlation for oil-refrigerant R134a mixture flashing flow in a small diameter tube
(Elsevier B.V., 2009-05-01)
This paper presents an experimental investigation of the ester oil ISO VG10/refrigerant R134a mixture flashing flow in a 6.0 m long, 3.22 mm ID tube, which is one of the primary steps towards the construction of a methodology ...

Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
Intergranular susceptibility in failures of high pressure tubes
(Elsevier, 2009-02)
This work addresses the influence of metallurgical susceptibility to intergranular cracking on the repeated cracking and failure of thick wall curved steel tubes from a petrochemical reactor. These tubes are made of HP-4 ...
