Effect of Residual Stress on Failure of Tube-to-tubesheet Weld in Heat Exchangers
In a shell and tube heat exchanger, the failure of tube-to-tubesheet welds results in high-pressure water jet which erodes the refractory in front of the tubesheet. Finite element method was employed to simulate the welding process and post weld heat treatment (PWHT) to find the factors affecting the failure in tube-to-tubesheet weldments. Residual stresses in two different geometries of tube-t...
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...
متن کاملDigital Radiographic Imaging Inspection System on The Tube to Tube sheet Welding Joints of Heat Exchanger
The tube to tube sheet welding joints of heat exchanger is the most critical joints. A special Nondestructive testing technology was proposed, which is based on the digital radiographic imaging automatic inspection system to the characteristics on the tube to tube sheet welding joints of heat exchanger. A new style Linear Diode Arrays as a device is used to receive ray, which will be fixed on a...
متن کاملNonlinear Control Of A Shell And Tube Heat Exchanger
The paper deals with design and simulation of nonlinear adaptive control of a shell and tube heat exchanger. The method is based on factorization of the controller on a nonlinear static part and an adaptive linear dynamic part. The nonlinear static part is derived using inversion and subsequent exponential approximation of simulated or measured steady-state characteristics of the exchanger. The...
متن کاملMinimization of Entransy Dissipations of a Finned Shell and Tube Heat Exchanger
Improving heat transfer and performance in a radial, finned, shell and tube heat exchanger is studied in this study. According to the second law of thermodynamics, the most irreversibilities of convective heat transfer processes are due to fluid friction and heat transfer via finite temperature difference. Entransy dissipations are due to the irreversibilities of convective heat transfer. There...
