OBJECTIVE During extracorporeal circulation design and orientation of aortic cannulae tips mainly determine flow pattern in the aortic arch and arch vessels which is the objective of this in vitro study, comparing single versus multiple stream cannulae. METHODS In an aortic arch glass model, jet streams of 21-24 French aortic cannulae which were inserted in the ascending aorta were directed a...
The pressure vessel design problem is a well-known design benchmark for validating bioinspired optimization algorithms. However, its global optimality is not clear and there has been no mathematical proof put forward. In this paper, a detailed mathematical analysis of this problem is provided that proves that 6059.714335048436 is the global minimum. The Lagrange multiplier method is also used a...
Development of Finite Element Based Wind and Seismic Design Procedure for Horizontal Pressure Vessel
The liner of a compressed natural gas pressure vessel is manufactured by D.D.I. (deep drawing and ironing), which continuous process that uses deep to reduce the diameter billet ironing thickness billet. In second stage existing process, two steps have been performed separately with different dies, requires long processing time, high manufacturing cost, installation space. To solve above proble...
This paper systematically discusses the significance of pressure vessel inspection, defines main body annual inspection vessel, and puts forward matters needing attention in process according to existing situation, so as provide a certain reference for smooth development vessels.
