A heat exchanger is a device used to transfer heat between two or more fluids. The fluids can be single or two phase and, depending on the exchanger type, may be separated or in direct contact. Devices involving energy sources such as nuclear fuel pins or fired heaters are not normally regarded as heat exchangers although many of the principles involved in their design are the same.

Internally, ANSYS FLUENT stores the computational mesh in meters, the SI unit of length. When mesh information is read into the solver, it is assumed that the mesh was generated in units of meters. If your mesh was created using a different unit of length (inches, feet, centimeters, etc.),

A large number of flows encountered in nature and technology are a mixture of phases. Physical phases of matter are gas, liquid, and solid, but the concept of phase in a multiphase flow system is applied in a broader sense. In multiphase flow,

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.

External flows past objects have been studied extensively because of their many practical applications. For example, airfoils are made into streamline shapes in order to increase the lifts, and at the same time, reducing the aerodynamic drags exerted on the wings.

Free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids, for example, liquid water and the air in the Earth’s atmosphere.

During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section’s critical geometric properties.

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.

The MultiZone mesh method provides automatic decomposition of geometry into mapped (sweepable) regions and free regions. When the MultiZone mesh method is selected, all regions are meshed with a pure hexahedral mesh if possible.

Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain

For solid models, meshing technologies from ANSYS provide robust, well-shaped quadratic tetrahedral meshing on even the most complicated geometries.

The CutCell meshing process involves the following approach:
Objects, material points (optional), and size functions are defined.
The initial size of the Cartesian grid is computed based on the minimum and maximum size set for the size functions.

The Body of Influence option is available in the Type field if you selected a body and Use Adaptive Sizing is set to No. Using this option, you can set one body as a source of another body (that is, a Body of Influence).

You can control three mechanisms in ANSYS Workbench that operate in a parallelized manner:
Remote Solve Manager Design Point updates. Refer to RSM Configuration.

Use the Open command to open files created in any supported format. Use the Save As command to export parts, assemblies, drawing sheets, and 3D markups to formats read by other applications. Your license type determines which of these actions are supported.

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

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.

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.

The Fill feature is located in the Tools Menu, and is available when the model consists of active and/or frozen bodies. The Fill feature is used to extract inverse volume or volumes enclosed within a body or a set of bodies.

The analysis tools consist of a set of functions which allow you to measure the distance between any two entities, obtain model entity information, and detect model faults. The function supports:

Use the Open command to open files created in any supported format. Use the Save As command to export parts, assemblies, drawing sheets, and 3D markups to formats read by other applications.

An enclosure is a solid around a body or bodies that has a cushion around the enclosed solid(s). The enclosure can be a box, cylinder, or sphere, as shown below.

The Combine Closed tool is used to make combinations of objects. You can add (or merge) objects together and you can subtract (or split) objects from each other. These actions are also known as Boolean operations.

Use the Split Body tool to split a body by one or more of its faces or edges. Then select one or more regions for deletion.

ANSYS SpaceClaim enables anyone to create, edit, or repair geometry without worrying about underlying technology. With SpaceClaim, working with 3D modeling software becomes fast, easy, flexible, and rewarding, no matter where in the workflow you need it.

Use the Volume Extract tool in the Analysis group on the Prepare tab to create a solid based on the volume enclosed by a single body or set of bodies (including meshes).

The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word “NACA”.

ANSYS ICEM CFD software supports a wide range of direct CAD interfaces and geometry readers, including faceted geometry and mesh readers.

ANSYS ICEM CFD software supports a wide range of direct CAD interfaces and geometry readers, including faceted geometry and mesh readers. Components from different formats can easily be combined within one meshing session.
