3. NATURE OF PHYSICAL PROBLEM SOLVED

Transient flow of subcooled or superheated water from a variable pipe area, using conduction dependent bubble growth. Initial conditions may include variable temperature along pipe length. The bubble growth phase eventually leads to droplets in vapour stage.

[ top ]

4. METHOD OF SOLUTION

Pipe is divided into Lagrangian mesh and the differential equations are replaced by finite difference equations.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM: Maximum number of meshes 130.

[ top ]

6. TYPICAL RUNNING TIME

Typically 5 minutes machine time per one millisecond real time.
