Short description and remarks

Engineering Point of view :
'Shell and Tube' Heat Exchanger are widely spread in the field of chemical engineering.Still it is not clear to arrange the tubes inside the apparatus in order to get a optimal
heattransferbehaviour.Beginning from a sample
configuration with only one tube (Rad=1.5) we studied
cases for 2X2 upto 5x5 tube arrangement for constant
circumference as well as constant area.
My task is Fluid flow calculation in a square
of 4 units with 3 circles in a row, accounting to 9 as
a total number.The circles are of 0.5 radii.The circles
are placed at equidistant from each other and the first
circle in the configuration is located at
x=0.75,y=0.75.

Mathematical point of view :
We studied a 2D cutplane of the
above described apparatus.Fluid flow calculation in a square of 4
units with one circle of radius 1.5,located at the center of square
i.e., at x=2 & y=2. calculation starts from rest.The calculations are
observed with Reynolds number, Re=1,000. This simulation is part of
a SoftwarePraktikum at the University of Dortmund in 2004'.
