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. The heat transfer can also take place within the system due to temperature difference at various points inside the system. The difference in temperature is considered to be ‘potential’ that causes the flow of heat and the heat itself is called as flux.
Modes of Heat Transfer
There are three modes of heat transfer between the two bodies: conduction, convection and radiation. These have been described below:
Conduction: The transfer of heat between two solid bodies is called as conduction. It depends on the difference in temperature of the hot and cold body. Example of conduction heat transfer is two bodies at different temperature kept in contact with each other. Another example is heating one end of the metal like copper; due to conduction heat transfer the other end of the metal also gets heated.
Convection: The transfer of heat between the solid surface and the liquid is called as convection heat transfer. Let us considering a vessel of water being heated, in this case heating of water due to transfer of heat from the vessel is convection heat transfer.
Radiation: When two bodies are at different temperatures and separated by distance, the heat transfer between them is called as radiation heat transfer. In case of the conduction and convection heat transfer there is a media to transfer the heat, but in case of the radiation heat transfer there is no media. The radiation heat transfer occurs due to the electromagnetic waves that exist in the atmosphere. One of the most important examples of radiation heat transfer is the heat of the sun coming on the earth.
In this tutorial you will learn to simulate heat transfer using Ansys CFX through one pipe in the wall. You can download the geometry from this link.
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 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.
You can set the Use Automatic Inflation control so that inflation boundaries are selected automatically depending on whether or not they are members of Named Selections groups.
Pipe wyes are used to to allow one pipe to join another pipe at some degree or angle. As the name suggests, the pipe wyes are Y-shaped pipe fitting devices.
You can make animations based on keyframes. Keyframes define the start and endpoints of each section of animation.
In this tutorial, you will learn how to use the Match Control tool in Ansys Meshing. Match Control allows duplicating the mesh in a body. We have two option Match Control Cyclic and Arbitrary.
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
The Sphere of Influence option is available in the Type field after you select an entity such as a body, face, edge, or vertex.
