ANSYS Fluent calculates the surface deposition rate (kg/m^2s) through a combination of user-defined settings and solver algorithms. The surface deposition rate represents the mass of a particular species deposited on a surface per unit area and time.

Here's an overview of the general steps and considerations taken by ANSYS Fluent to calculate the surface deposition rate:

Define the Species and Surface Interaction:In ANSYS Fluent, you need to define the species that are involved in the deposition process. This can be done by specifying the relevant chemical species and their properties, such as density, diffusivity, and deposition velocities.

Set Up the Appropriate Boundary Conditions:For surface deposition, appropriate boundary conditions need to be set on the surfaces where deposition is expected to occur. These boundary conditions may include specifying the deposition flux or specifying the deposition rate at the surface.

Solver Settings:Fluent uses numerical methods to solve the governing equations, which include the species transport equation. The solver discretizes the equations and iteratively solves them to obtain a solution for the species concentration field.

Surface Deposition Model:The actual deposition model used in Fluent can vary depending on the type of deposition (e.g., particle deposition, condensation, etc.) and the physical processes involved. Fluent provides different deposition models, such as the discrete phase model (DPM) for particle tracking and deposition.

Calculation of Deposition Rate:As the solver iterates through the time steps, it calculates the species concentration at the surface cells. Based on the specified deposition model and the properties of the species and surface, Fluent calculates the deposition rate on each surface cell.

Integration Over Surface Area:The surface deposition rate is typically calculated as a spatial average over the surface area. Fluent integrates the local deposition rates over each surface cell and then divides it by the surface area to get the average surface deposition rate (kg/m^2s).

It's important to note that the actual implementation and options available in ANSYS Fluent might change with different versions and updates of the software. Therefore, for the most accurate and up-to-date information, it is always recommended to refer to the official ANSYS Fluent documentation or user guide specific to the version you are using.
