Computational fluid dynamics (CFD) is a powerful technique for predict
ing fluid flow and heat transfer in engineering systems. Exemplars are
presented to demonstrate the relevance of CFD to mechatronics. Popula
r CFD techniques and commercial packages are discussed. Predictions re
levant to pneumatic actuators, magnetic bearings, enclosures containin
g electronic components, solar-concentrators and inert gas electronic
insulation are presented. The exemplars chosen illustrate the predicti
on of: unsteady; three dimensional; turbulent; moving boundary; forced
convection and free convection flows. The amount of time required to
set up and run the exemplars is given and on average this is 12 min an
d 2.5 h, respectively.
