Heating oil, thermography
Référence de la vidéo 12371295
| Thermographic footage of the surface of oil as it is heated from below. In this footage, the hotter the oil is, the brighter it appears. Hot oil from below rises to the surface as it is less dense than cooler oil. Once at the surface it spreads and cools down, sinking around the rising plume. This is called Rayleigh-Benard convection, and it is seen wherever a fluid is heated from below. A similar process is seen on the surface of the Sun with rising plumes of hot plasma, where it produces a pattern of cells called granulation. | |
