NUMERICAL INESTIGATION OF ISOTHERMAL FLOW AROUND IMPINGEMENT PLATES IN A SHELL AND TUBE EXCHANGER
NUMERICAL INESTIGATION OF ISOTHERMAL FLOW AROUND IMPINGEMENT PLATES IN A SHELL AND TUBE EXCHANGER
The impingement plate is an important protecting device of tube bank
which is located on shell side at the nozzle inlet of shell and tube heat
exchanger. Current work presents a 2D numerical investigation of the flow
structure developing around different impingement plate design under different
flow conditions using ANSYS Fluent. Location, size and arrangement of
impingement plate are the investigated parameters which provides significant
information for the selection of ideal location and size of required
impingement plate. Study compares different
plate geometry and concludes the best one which apart from protecting the tube
banks, also removes the stagnation zone developing behind them because of their
placements.
