CONCLUSIONS
On the basis of calculations performed the following conclusions can be
drawn:
- Application of the concept of transfer function is a very effective
technique to develop precise version of the model. Properties of
transfer functions help to examine many model versions and to ensure
choice of the best one.
- Interactions between elements of the empty sample tube strongly
influence results and the more complex model B is recommended; model A
is of less precision.
- If the first element of sample tube includes a bed, interactions
between elements are strongly reduced and simpler model A can be
recommended; model B is of comparable precision to model A.
- In all cases, very good fit between numeric and experiment curves were
obtained.
- den Iseger algorithm ensures fast calculations of good precision and
can be recommended for application; the algorithm is a very effective
for distributed parameters systems.
- The method presented is a quick procedure to determine of gas flow
parameters and it is faster comparing to other methods previously
described in literature. It can be an alternative for using CFD
programs.
- The Computer Algebra System (CAS) - MapleĀ® is very helpful for fast
and error free derivation of very complex transfer functions for
distributed parameters models.
