Performance Assessment of Double Corrugated Tubes in a Tube-In-Shell Heat Exchanger
نویسندگان
چکیده
In this article, the performance of double corrugated tubes applied in a tube-in-shell heat exchanger is analysed and compared to equipped with straight tubes. The CFD (computational fluid dynamics) analysis was performed considering turbulent flow regime at several mass rates. It observed that geometry does not have significant impact on pressure drop inside exchanger, while it has potential increase its thermal by up 25%. ε–NTU (effectiveness–number transfer units) relation also demonstrates advantage using exchangers over

Investigating 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 کاملEffect of baffle oientation on shell tube heat exchanger performance
In this paper, fluid flow and heat transfer in the laboratory (small size) shell tube heat exchanger are analysed by computational fluid dynamic software. In this type of shell tube heat exchanger baffles with different angles of rotation: 00 (horizontal segmental baffle), 150 (from horizontal), 300, 450, 600, 750, 900 (vertical segmental baffle) is used. Effect of baffle orientation on shell t...
