Two cylinders side by side
Aim: See how two nearby bodies interact in a flow.

📘 Theory
Close cylinders interact: the gap flow can bias to one side and the wakes couple, changing drag and shedding compared with a single cylinder. Important for tube bundles and offshore risers.
gap ratio = spacing / diameter
🧰 Apparatus (virtual)
- Wind tunnel
- two cylinders
📝 Procedure
🎤 Viva questions
Why do heat-exchanger tubes vibrate
Wake interaction and vortex shedding in tube bundles.
What is flip-flopping flow
The gap jet switching between the two sides.
🛡️ Safety
Virtual by default. Machine shops, CNC, presses and test rigs need instructor supervision, PPE and machine-specific safety training.
