Natural Convection from a Horizontal Heat Sink: Numerical simulation using Fluent 19.2

Natural convection is a phenomenon occurs when heat is transferred to a fluid, which raises its temperature and decreases its density and consequently makes it flows upward. This book is a complete tutorial on how to simulate this kind of phenomenon using ANSYS Fluent 19.2. This is applied to a simple application of cooling a small surface using a finned heat sink. The tutorial starts with creating the 3D domain itself inside ANSYS DesignModeler, then discretizing it (Meshing) in ANSYS Meshing application. After that, the model is defined in Fluent with the appropriate boundary conditions. Finally, the output data is processed in Fluent to see the resulting flow around the heat sink and the temperature distribution in both the fluid and the heat sink itself.
The steps are illustrated in the form of high-resolution screenshots of the applications' windows. Also, they are preceded by a textual description of the steps and some of them are followed by an explanation of the reasons behind the different choices.
