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 کاملNDE Techniques for Reliable Inspection of Carbon Steel Tubes
Ferromagnetic tubes in Heat Exchangers, Boilers, Air Fin Coolers are most common in the Petrochemical Industry. Carbon Steel, an inexpensive material has good mechanical properties and heat transfer capabilities. However, it is often employed in conditions where corrosion if it sets in, acts very fast. Over the years with shrinking maintenance budgets and longer intervals between plant shutdown...
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 کاملDevelopment of an Eddy Current Probe for Detecting Outside Circumferential Cracks near an Expansion of Heat Exchanger Tubes
Eddy current testing (ECT) is a conventional inspection method of heat exchanger tubes. Many types of probes have been developed depending on such tube conditions as tube shapes and materials. However, the vicinity of a tube expansion is still a difficult area to inspect. This is because there is a step-shape variation circumferentially on the inside surface and there is a ferromagnetic tube sh...
