Effect 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 کاملCFD Analysis of Combined Serial Two Shell Pass Shell and Tube Heat Exchanger with Continuous Helical Baffles
In the present era where energy demands are growing everyday it has become very important to capture every available energy from the hot source and utilize it for the process with minimum wastage. With this view, the combined serial two shell pass shell and tube heat exchanger (CSTSP) concept had been put forward and simulated using Fluent. Though the novel model of the heat exchanger has a hig...
متن کاملEffect of Corrugated Baffles on the Flow and Thermal Fields in a Channel Heat Exchanger
The performance of corrugated baffles inserted in a rectangular channel heat exchanger is investigated. The fluid flows and thermal distribution are determined via numerical simulations. The working fluid has a shear thinning behavior. The influence of the baffle design is explored, we interest to the “wavy” shape. The corrugation angle of baffle (α) is changed from 0° (i.e. a straight...
متن کاملOptimal Design of Shell-and-Tube Heat Exchanger Based on Particle Swarm Optimization Technique
The paper studies optimization of shell-and-tube heat exchangers using the particle swarm optimization technique. A total cost function is formulated based on initial and annual operating costs of the heat exchangers. Six variables – shell inside diameter, tube diameter, baffle spacing, baffle cut, number of tube passes and tube layouts (triangular or square) – are considered as the design para...
