This flow visualization shows why shape matters in fluid dynamics 🌊💨 When fluid (air or water) flows past an object, two big things control drag: • Pressure differences • Flow separation & vortices 🟥 Square object Sharp edges force the flow to separate early → large turbulent wake → strong pressure drag. Those swirling vortices behind it? That’s lost energy. ⚪ Circular object Smooth curvature lets the flow stay attached longer → smaller wake → lower drag coefficient. That’s why: • Cars are rounded • Aircraft fuselages are cylindrical • Tall buildings often have chamfered or curved edges Same size. Same speed. Wildly different physics. 💬 Comment: What shape do you think has the lowest drag — sphere or teardrop? 🔁 Remix / Share if fluid dynamics just clicked 📌 Save for later #STEM #FluidDynamics #PhysicsExplained #Engineering #Aerospace
