The course introduces the basics of the numerical heat
and fluid flow modelling to
engineers who are new to this field or CFD simulations
are not their main
occupation. The workshop consists of the theoretical
(physics+numerical models), review
and practical part with hands-on computer exercises.
In contrast to the standard CFD-software vendor
workshops, we focus on the general idea
of flow modelling rather than the operation of the
specific software.
