Abstract


As an important process machine, heat exchangers are widely used in petroleum, chemical, power machines and other process industries. The rational design of shell-and-tube heat exchangers not only have a great impact on enhancing the performances of heat exchangers and increasing the producing efficiency and economy of the domain, but also reducing energy and metal consumption. So the study in the rational design of shell-and-tube heat exchangers has significant meaning for scientific research and engineering application.Taking shell-and-tube heat exchangers with single segmental baffles as research object, this paper analysed all kinds of design method and proposed a more accurate design method-stepwise calculation method according to the domestic and foreign published literatures. This whole heat exchanger is firstly divided into several subsections based on the strcture. Each subsection units was calculated by the current physical properties, the detail distribution of heat transfer coefficent and pressure drop can be obtained. Compared with the results of HTRI, relative error is less than 0.1% for tubeside, less than 10% for shellside. It’s proved that the design method feasible and accurate.In order to verify the proposed design method, three dimensional physical models of shell-and-tube heat exchanger were built for numerical simulation. This paper studied shellside turbulent flow and heat transfer characteristics of shell-and-tube heat exchanger by applying computational fluid dynamics (CFD) software Fluent.
