shell-side flow field in the disk-and-donut heat exchanger. Also computation of the fields of the shell-side and tube-side temperature.
Transonic Flow
Steady compressible flow through a converging-diverging nozzle. Treatment of highly

Power-Plant Discharge
An illustration of the use of mass sources and sinks in a two-dimensional
calculation. Flow is created due to the discharge of warm water into a lake and intake of cold water. Temperature field is determined by the discharge temperature and the heat

sudden expansion. An illustration of the use of the four-flux radiation model with an absorbing-scattering medium.
