  1. 2. – A dimensionless number that describes the lift characteristics of an airfoil.
  2. 3. – The undisturbed flow of fluid far from the influence of obstacles or boundaries.
  3. 5. – A type of smooth, orderly flow where fluid moves in parallel layers.
  4. 6. – A measure of the rotation of fluid particles in a flow.
  5. 8. – The phenomenon where the fluid flow detaches from the surface of a body, creating turbulence.
  6. 11. – The point on a surface where the fluid velocity is zero.
  7. 13. – A dimensionless number that describes the drag characteristics of an object moving through a fluid.

Down
  1. 1. – The area of turbulent flow that forms behind a body moving through a fluid.
  2. 4. – A flow regime where the flow velocity is less than the wave speed, leading to steady and stable flow.
  3. 7. – A dimensionless number used to predict flow patterns in different fluid flow situations.
  4. 9. – A body shape that causes a significant flow separation and large wake, often used in fluid dynamics.
  5. 10. – A measure of a fluid's internal resistance to flow, or its "thickness."
  6. 12. – The branch of physics concerned with the relationships between heat and other forms of energy.
