Examples of results of the dolfyn version of April 2006:
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).|
|Turbulent flow around a wall. This was a test of a large model consisting of over 500,000 cells (34 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.|
