Computational PDEs Unit: Jet problem
Jet problem
(Back to the CPDE Unit Home Page)
This is a recent collaborative project with the
School of
Chemistry to
provide computational support to their
FAGE
experiments. The
experiments involved forming a steady jet by passing air at atmospheric
pressure through a nozzle into a low pressure region. The process was
computationally modelled using a Riemann problem based algorithm on a 2-D
axisymmetric fixed Cartesian grid in order to ascertain the exact jet
structure (see [46]).
Similar problems are now being solved on adaptive unstructured meshes
using the SPRINT2D software.
The figure below shows the calculated temperature profile of such a jet.
Blue represents the
ambient temperature and red the lowest temperature. The shock
structure can be clearly seen.
