Abstract

Abstract: Heat exchangers are common devices on board' ships, but also in the oil-chemical industry. In this paper is presented an U-tube heat-exchanger that was designed with NX Siemens. The component parts of this heat exchanger, the CAD models and their assembly mode in the final part are presented. It is known that the design of a heat exchanger is a real challenge, and the dimensions of the component parts are established according to some standards, engineering design guidelines and to the industrial domain where they are used. The dimensions of our device were established by the author by consulting specialized works. The details of how the component parts were designed, the CAD instructions used and the constraints applied to the component parts in the final assembly are presented in details. Subsequently, the final assembly is taken over in ANSYS where a CFX analysis of fluid flow is performed and a study of the heat transfer between the two fluids.
