Reynolds number Memes

Praying for laminar flow but getting turbulence instead is the fluid dynamics equivalent of ordering a salad and receiving a deep-fried Mars bar. For the uninitiated, Reynolds number is that sneaky parameter that determines if your fluid will flow smoothly like honey (laminar) or chaotically like a mosh pit (turbulent). When it's high, your carefully planned experiment becomes absolute chaos—much like trying to organize a kindergarten class after feeding them pure sugar. Engineers everywhere are nodding in silent trauma while remembering that time their beautiful simulation turned into what can only be described as "mathematical jazz."
