Ansys CFX Tutorial | Flow through Porous Media

In this tutorial you will learn how to simulate a Flow through Porous Media using Ansys CFX.

Ansys CFX – NACA 4412 (Structured Mesh)

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.

OpenFOAM vs ANSYS CFX

OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organisations.

BladeGen + Turbogrid + Ansys CFX – Centrifugal Pump

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.

Ansys CFX – Compressible Flow

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.

Ansys CFX – Heat Transfer through a Pipe

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.

Ansys CFX – Heat Exchanger (Shell & Tubes)

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.

Ansys CFX – Vortex Generator 3D

In fluid dynamics, a vortex is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.

Ansys CFX – How to add new material?

By default, your local materials list will include a single fluid material (air) and a single solid material (aluminum). If the fluid involved in your problem is air, you can use the default properties for air or modify the properties.

Ansys CFX – Free Surface 3D

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.

Ansys CFX – Heat Transfer Fluid/Solid

Ansys CFX – Heat Transfer Fluid/Solid

Heat transfer is the process of transfer of heat from high temperature reservoir to low temperature reservoir. In terms of the thermodynamic system, heat transfer is the movement of heat across the boundary of the system due to temperature difference between the system and the surroundings.

Ansys CFX – Flow around a Cylinder / Parameters DesignPoint (DP)

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.

Ansys CFX – NACA 0012 with Angle of Attack (AOA)

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.

Ansys CFX – Centrifugal Pump & Cavitation

Ansys CFX – Centrifugal Pump & Cavitation

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. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.

Ansys CFX – Porous Medium

Ansys CFX – Porous Medium

A porous medium is a solid with voids distributed more or less uniformly throughout the bulk of the body.

The basic characteristic of this medium is porosity. The bulk porosity Π of a material is defined as the ratio of void volume Vv to body volume V0, Π = Vv/V0. Since the remaining portion Vs of the total volume of the material is in the form of a solid “skeleton”, then

Ansys CFX – Import Pressure to Ansys Mechanical (FSI)

Fluid-structure interaction (FSI) is the multiphysics study of how fluids and structures interact. The fluid flow may exert pressure and/or thermal loads on the structure. These loads may cause structural deformation significant enough to change the fluid flow itself.

Ansys CFX – CD Nozzle (De Laval Nozzle)

Ansys CFX – CD Nozzle (De Laval Nozzle)

A nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow. Ramjets and rockets typically use a fixed convergent section followed by a fixed divergent section for the design of the nozzle. This nozzle configuration is called a convergent-divergent,
