lift force

lift force

force between a moving object and its surrounding medium that acts at right angles to the direction of travel of the object; may be influenced by its shape, by its angle of orientation to the direction of flow past it of fluid (liquid or gas), or by spin. See also Magnus force.

The basic principle of a wind turbine is a rotating turbine shaft ability caused by the vector of the lift force and drag force generated due to the aerodynamic shape of the blade cross section.
Covering first irrotational flow motion of an ideal fluid, then the theory and applications of real fluid flows, he discusses such topics as ideal fluid flows and irrotational flow motion; basic equations and flow analogies for two-dimensional flows; Joukowski transformation, the theorem of Kutta-Jourkowski, and lift force on an airfoil; and turbulence, and applying boundary layer theory to laminar boundary layer flows.

When such a lift force is the dominant upward force, the role buoyancy plays in keeping the hull afloat is reduced.
These flows are very complex and influenced by various physical phenomena, such as particle-turbulence and particle-particle interactions, deposition, by gravitational and viscous drag forces, particle rotation, and lift force.
The PZ linkage also offers large breakout force and a 10 percent increase in lift force, which not only makes bucket filling quicker and easier but also improves digging performance.
There will be a resultant force directed upwards, ie a lift force.
If the ball is made to spin, then a lift force is generated that will cause the ball to move sideways, or dip, depending on the spin direction.
Modeling indicated that an asymmetrical deflection of light would create a surprisingly stable lift force.
The test objectives will measure the total lift force generated by the airflow velocities, as well as the various angles of attack at various temperatures and relative humidity.
