Numerical Analysis of Shell-Side Fluid Flow in Shell-and-Tube Heat Exchanger
This work presents velocity field and flow resistance analysis on shell-side of shell-and-tube heat exchanger. Numerical investigations have been carried out using a finite volume method implemented in ANSYS Fluent code. In case of heat exchangers with a great number of tubes in bundle, the finite volume method numerical model representing real geometry of the apparatus becomes very complex and results in a high computing power demand. To overcome the above difficulty, an attempt has been made to represent the tube bundle using the continuum approach. The resulting pressure drop values have been compared with e.g. calculation results using HTRI code and exemplary values obtained from the real apparatus.
