In this video, we explore the fascinating phenomenon of Bénard cells — the beautiful convection patterns that arise when a fluid is heated from below and cooled from above. We'll dive into the theoretical background, the physics behind the pattern formation, and explain the role of the Rayleigh number, buoyancy forces, and stability in this classic natural convection problem.
🎓 What You’ll Learn:
What are Bénard cells?
How thermal gradients lead to convection rolls
The significance of the Rayleigh number
Governing equations and Boussinesq approximation
Real-world relevance of Bénard convection
📊 Ideal for:
Engineering students
Physics enthusiasts
CFD beginners
Researchers working in fluid dynamics or heat transfer
🛠️ Tools used: OpenFOAM (optional for simulation)
