|
| Turbulent flow around a car (123 kB). |
|
Examples of results of the dolfyn version of September 2004:
| Turbulent flow around a car at 108 km/hr (109 kB). |
|
| Turbulent flow through a channel (69 kB). |
|
| A stagnant flow is a good test because the pressure rise can be calculated by hand (Bernoulli) and the isobars are circles (86 kB). |
|
| This is a simple test with a bad mesh('rough grid'). This example can be found in: P. Wesseling, 'Principles of Computational Fluid Dynamics', chapter 13.6, fig. 13.12 (35 kB) |
|
| Turbulent water flow through a device (63,000 cells, 86 kB). |
|
| Turbulent kinetic energy of a turbulent flow around a mirror (Jos van Heck, 38 kB). |
|
| Turbulent flow through a tube (74 kB). |
|
| A well known classic; the 'backwards facing step' (2480 cells, 47 kB). |
|
| The 'backwards facing step' with more detail (8240 cells, 50 kB). |
|
| A test with a strongly distorted mesh; a 'lid driven cavity' under 45° (1942 cells, 34 kB). |
|
| Unsteady cooling down in a tube. At time t = 0 cool air enters the 10 degrees warmer tube (74 kB). |
|
| Thermal buoyancy in a room; to the left a cold wall and to the right a warm wall (29 kB). |
|
| Buoyant flow along a hot cylinder (10 kB). |
|
| Flow through a heatexchanger (37 kB). |
|

|
| Test of an unstructurerd model (1) (28475 hexa's, 7827 prism's, 2850 pyramid's, 168 tetra's; 50 kB). |
|
| Test of an unstructurerd model (2) (89330 hexa's, 3067 prism's, 1468 pyramid's, 266 tetra's; 38 kB). |
|
| Unsteady flow around a cylinder at Re = 100 (von Karman-vortexstreet); the result is a Strouhal number of St = 0.17 (186 kB). Click here for similar examples. |
