This is TYCHO simulation of a wind-channel with hot (1300 K) obstacles in the wind stream. The temperature evolution of 0.15 sec real-time is shown. In the beginning a first shock is moving over the structure. This switch-on shock is followed by a 10 m/s wind emerging constantly from the left boundary. As the wind moves over the hot obstacles the air around the obstacles becomes cooler. After ~0.1 seconds the complex, turbulent airflows around the obstacles start to vanish and a constant stream cools the air in the computational domain. This is a 2D simulation done with a TYCHO, you can find this simulation setup in the examples directory of TYCHO (cooling2).
