Radiator Game - Episode 3 Modern Wall - CHT in Fluent

In today's episode of Radiator Game I would like to present you a thermal analysis of a room for walls insulated in a modern way, i.e. with polystyrene and cellular concrete. Of course, we will perform the simulation using the virtual layers method on the boundary condition of the model walls.

How to... make 3D any variable distribution in Ansys postprocessing

A very interesting option in post-processing in Ansys is the generation of 3D distributions that can be easily done using the IsoSurfaces function. We can distribute any variable by defining ranges of values of different sizes. The entire graphic design of the generated distribution also depends on us. When it comes to IsoSurfaces, we have a very wide range of modular possibilities with this function.

Radiator Game - Episode 2 - CHT in Fluent

In the second part of Radiator Game I would like to show you a different approach to modulating insulation on walls or heat flow resistance on windows using defined virtual layers in Ansys Fluent. In this regard, this program offers many more possibilities than the good old CFX.

Radiator Game - Episode 1 - CHT in Fluent

In today's post and a few more, I will introduce you to the FEA modeling of CHT analysis in Fluent, a very common phenomenon, which is heating a room with a radiator. In the first part, we will determine the heat losses on the walls of the building with very simple dependencies and we will perform a preliminary CHT analysis of heating the room with a radiator.

How to... simulate Bullet in Ansys Fluent Tutorial

In today's post, I would like to show you a tutorial on how to model a bullet flight in Ansys Fluent. Due to the earlier post where the bullet was modeled in the SimScale software, it will be an interesting comparison, especially when it comes to gas velocity distributions.

CFD Rivals - CHT Analysis - CFX Tutorial Step-By-Step

 Today I would like to introduce you to the CHT simulation tutorial in CFX. This is the missing link to the previous two entries. In CFX, CHT analysis is defined a bit differently than in Fluent.
