ANSYS FLUENT – Heat Exchanger

October 26, 2018

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.

Design Modeler – Symmetry

June 16, 2018

The Symmetry feature is a tool used to define a symmetry model. The feature takes either all the bodies or selected bodies of the model as input and accepts up to three symmetry planes. You can choose either full or partial models to work with. If a full model is used, the selected symmetry planes will slice off the model and only a portion of the model will be retained. The valid body types for this feature are surface and solid.
