Case Studies Analysis of a Home Appliance
Ceiling fans (even now) are designed by trail and
error. Typically each fan consumes less than 70
watts Efficiency of conversion can be less than
10 Efficient fan design is therefore very
competitive CFD algorithm for unsteady
simulation may run for two weeks.

Case Studies - High Fidelity Simulation
Pressure variation on the fuel pins due to flow
of liquid sodium Note the spacer wire which
complicates the analysis
Flow direction
Hydraulics and thermal simulation in nuclear
reactor. Liquid sodium is used for heat
extraction Zeus has simulated 219 pin bundle,
which no other group has simulated

Largest Numerical Simulation (in Nuclear Energy)
in world!
Surface Meshes for 91 It is difficult to mesh
for more than 9 fuel pins ! Zeus generated Mesh
for 217 pins!!
Smoothened meshes at intermediate section
