Study of 'Shell and Tube' Heat-Exchanger exhibiting different tube arrangements(height 4, width 4)

• Engineering point of view:
  

  shell and Tube'-Heat-Exchanger are widely spread in the field of chemical engineering. Still it is not clear how to arrange the tubes inside the apparatus in order to get a optimal heat-transfer-behaviour.Beginning from a simple configuration with only one tube (Rad=1.5; area = pi*RAD^2)we studied cases for 2x2 upto 5x5 tube arrangements for constant circumference as well as constant area

• Mathematical point of view:
  
  we studied a 2D cutplane of the above described apparatus. Fluid flow calculation in a square of 4 units with four circles each of radius 0.75, and the centre of first circle located at x = 1, y = 1 The calculation starts from rest. The calculation is observed with Reynolds number, Re=1,000. This simulation is part of a Software-Praktikum at the University of Dortmund in 2004.
