The NACA four-digit wing sections define the profile by:
First digit describing maximum camber as percentage of the chord.
Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.

Compressibility effects are encountered in gas flows at high velocity and/or in which there are large pressure variations. When the flow velocity approaches or exceeds the speed of sound of the gas or when the pressure change in the system ( $\Delta p /p$) is large, the variation of the gas density with pressure has a significant impact on the flow velocity, pressure, and temperature.

Thermodynamics is a branch of physics that deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system that we can observe and measure in experiments. In aerodynamics, we are most interested in the thermodynamics of propulsion systems and high speed flows.

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers.

Slices bodies into multiple pieces. Active bodies in the Slice operation will be automatically frozen. This option is available when at least one body is present in the model.

Autodesk Inventor is a comprehensive and flexible set of software for 3D mechanical design, simulation, tooling creation, and design communication.

The Thin/Surface feature allows you to convert solids into thin solids or surfaces. The feature can operate on both active and frozen bodies. Typically, you will select the faces to remove, and then specify a face offset that is greater than or equal to zero (>=0).

The Body Operation feature allows you to manipulate bodies. Any type of body can be used with body operations, regardless of whether it is active or frozen. However, point feature points (PF points), attached to the faces or edges of the selected bodies, are not affected by the body operation.
