Laminar VS Turbulent Flow
Laminar Flow
What is Laminar Flow?????
Porsche
Porches are made for speed, and aerodynamics play a major role in the MAX speed of a car. The more aerodynamic a car is; the faster it can move. This is why this car is designed in a sleek manner, to reduce turbulent flow between air and the car. As shown in the picture above, this car is clearly aerodynamic, with little to none eddies
Plane Wing
Since planes fly in the air, being aerodynamic is one of the key factors that let it stay in the air. As you can see the wing is designed in a manor so that friction or drag (turbulent flow) is reduced, and laminar flow is increased.
Bullet
Bullets have to travel the fastest out of all Man-made goods. Therefor they must be aerodynamic, in order to reach there target. They must also travel in a straight line, for proper aim. That is why bullets are designed in a aerodynamic manor, to reduce Turbulent flow, and increase Laminar flow.
Turbulent flow
What is Turbulent Flow???
Turbulent Wake
A motor boats propeller is designed to push water back, effectively pushing the boat foreword. Eddies are creating by the propeller, when it pushes water backwards. This no effect on speed, as the water is cleared of the boat when it turns in to turbulence flow.
Smoke
Smoke being being made of carbon dioxide, and carbon dioxide being more dense than air would rise. When smoke rises it changes from laminar to turbulent flow, as the smoke particles dissipate among the oxygen particles.
Tennis Ball
Tennis Ball are more or less aerodynamic, although they have never achieved the aerodynamic harmony that gulf balls hold. As seen in the picture, the ball is releasing eddies that are moving back toward the ball, slowing it down.
