What if my Ansys Fluent model includes heat transfer?
When your Ansys Fluent model includes heat transfer you will need to enable the relevant physical models, supply thermal boundary conditions, and enter material properties (which may vary with temperature) that govern heat transfer. For information about heat transfer theory, see Heat Transfer Theory in the Theory Guide.
Does Ansys Fluent under-relaxe enthalpy?
When the enthalpy form of the energy equation is solved (that is, when you are using the non-adiabatic non-premixed combustion model), Ansys Fluent also under-relaxes the temperature, updating the temperature by only a fraction of the change that would result from the change in the (under-relaxed) enthalpy values.
Does Ansys Fluent include viscous dissipation terms?
As noted in Inclusion of the Viscous Dissipation Terms in the Theory Guide, the viscous heating terms in the energy equation are (by default) ignored by Ansys Fluent when the pressure-based solver is used. They are always included for the density-based solver.
Which cavity design is considered a heat transfer study?
Despite the existence of several review studies in the open literature, there is no specific review of heat transfer investigations that consider different cavity designs, such as spheres, squares, trapezoids, and triangles.
Do Ansys Fluent models with fins outperform other models with varying geometries?
Five different models with varying geometries and heat source configurations were designed and analyzed using CFD simulation in ANSYS Fluent. The results indicate that models with fins on the heat source surface outperform those without fins, due to increased heat transfer surface area.
Can natural convective heat transport be simulated in triangular cavities?
In a numerical study of natural convection in a cavity, Wijayanta () found a solution to the thermal analysis problem. The authors proposed simulating laminar natural convective heat transport in triangular cavities using the direct meshless local Petrov-Galerkin technique in conjunction with an implied reproduction model.
