Calculation of the flow in the entrance region of a rectangular duct with a moving wall.
Finned Tube
Laminar flow and heat transfer in the entrance region of a finned tube.
Tilted Cylinder
Calculation of buoyancy driven flow in a tilted cylinder with hot and cold ends.
Sudden Expansion

Calculation of flow and heat transfer in a
rotating duct. An illustration of flow computation in a rotating coordinate system.
Semicircular Duct
Mixed convection in a semicircular duct with a heated patch on the bottom surface.
Jet in Crossflow
Complex flow resulting from a jet issuing
into a duct with throughflow. Another illustration of the use of the k-e model for turbulence.
Shell-and-Tube Heat Exchanger
Use of the
distributed resistance concept is illustrated. Computation of the shell-side flow and temperature on both shell and tube side.
Array of Heated Blocks
Computation of periodically fully developed flow through an array of heated blocks.
Can Combustor
Calculation of the flow,
temperature, and mass fractions of reacting species in a combustor.

Flow around an agitator with an oscillating spindle. An
illustration of time varying velocity boundary condition.

Pumping of a compressible fluid into a cylindrical tank. An
illustration of unsteady compressible flow.
Converging-Diverging Nozzle
Transonic flow through a converging-diverging nozzle. Computation of
highly compressible flow.
Mass Sources and Sinks
Flow in an enclosure created by a discharge from a pipe. Illustrates treatment of mass

Radiation Heat Transfer
Radiation heat transfer from hot gases to the cold walls of a sudden expansion. Al illustration of
the use of six-flux radiation model with an absorbing-scattering medium.
Marangoni Convection
Calculation of surface tension and buoyancy
driven flow in a liquid metal. Shear stress results from variation of surface tension with temperature.
Melting of a Solid
Transient melting
driven by natural convection in the liquid. The phase change process is modeled using the enthalpy-porosity technique.
