  2. Coandă effect - Wikipedia

    en.wikipedia.org/wiki/Coandă_effect

    The force on the vessel generated by a propeller is a function of the speed, volume and direction of the water jet leaving the propeller. Under certain conditions (e.g., when a ship moves through water) the Coandă effect changes the direction of a propeller jet, causing it to follow the shape of the ship's hull.

  3. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle is a key concept in fluid dynamics that relates pressure, density, speed and height. Bernoulli's principle states that an increase in the speed of a parcel of fluid occurs simultaneously with a decrease in either the pressure or the height above a datum. [1]:

  4. Fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Fluid_dynamics

    In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).

  5. Wingtip vortices - Wikipedia

    en.wikipedia.org/wiki/Wingtip_vortices

    A NASA study on wingtip vortices, illustrating the size of the vortices produced. Wingtip vortices can pose a hazard to aircraft, especially during the landing and takeoff phases of flight. The intensity or strength of the vortex is a function of aircraft size, speed, and configuration (flap setting, etc.).

  6. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    Lift is defined as the component of the aerodynamic force that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction.. A fluid flowing around the surface of a solid object applies a force on it.

  7. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    The point of maximum aerodynamic load is often referred to as max q and it is a critical parameter in many applications, such as launch vehicles. Dynamic pressure can also appear as a term in the incompressible Navier-Stokes equation which may be written:

  8. Static pressure - Wikipedia

    en.wikipedia.org/wiki/Static_pressure

    In Aerodynamics, L.J. Clancy [1] writes: "To distinguish it from the total and dynamic pressures, the actual pressure of the fluid, which is associated not with its motion but with its state, is often referred to as the static pressure, but where the term pressure alone is used it refers to this static pressure."

  9. Pressure coefficient - Wikipedia

    en.wikipedia.org/wiki/Pressure_coefficient

    All the three aerodynamic coefficients are integrals of the pressure coefficient curve along the chord. The coefficient of lift for a two-dimensional airfoil section with strictly horizontal surfaces can be calculated from the coefficient of pressure distribution by integration, or calculating the area between the lines on the distribution ...
