Review Heat Exchanger: Research Development of Self-rotating Inserts in Heat Exchanger Tubes
Heat exchangers are widely used in power engineering and industrial applications, many techniques such as coiled tube, surface tension devices, rough surfaces, extended surfaces have been investigated to enhancethermal performance and to minimize the cost and size of the heat exchanger equipment. One of the most important techniques is tube insert. In general,tube inserts can be classified into...
متن کاملNumerical and heat transfer analysis of shell and tube heat exchanger with circular and elliptical tubes
Background: Heat exchanger is a device in many industrial applications and energy conversion systems. Various heat exchangers are designed for different industrial processes and applications. Shell and tube heat exchanger (STHE) has its own importance in the process industries. Methods: Experimental and numerical simulations are carried for a single shell and multiple pass heat exchangers with ...
متن کاملInvestigating Tubes Material Selection on Thermal Stress in Shell Side Inlet Zone of a Vertical Shell and Tube Heat Exchanger
In this study, the effect of the tube material on the thermal stress generated in a vertical shell and tube heat exchanger is investigated. Shell and tube heat exchangers are the most common heat exchangers used in industries. One of the most common failures in these exchangers in the industry is the tube failure at the junction of the tube to tubesheet. When the shell side and the tube side fl...
متن کاملSound Propagation through a Heat-exchanger Tubes Array in Power Boiles
In this paper, a mathematical model of leakage sound propagation through a heat exchanger tubes array in boilers is established, which is based on the Twersky’s sound scattering theory, transmission grating diffraction theory, Fabry-Perot’s interference principle, and algebraic iteration method. The tubes array is made up of large number periodically arranged tubes immersed in air. Its acoustic...
