💥💥💥 What is species model in Ansys Fluent and what is use for ? 🧐

Species model in Ansys Fluent is a feature that allows you to model the mixing and transport of chemical species by solving conservation equations describing convection, diffusion, and reaction sources for each component species¹. You can use this model to simulate non-reacting or reacting flows, with reactions occurring in the bulk phase, on wall or particle surfaces, or in the porous region². You can also choose different reaction mechanisms and rate formulations to suit your problem³.

Some examples of applications that use species model in Ansys Fluent are:

- Combustion modeling using finite-rate chemistry²

- Chemical vapor deposition (CVD) processes²

- Fuel cell modeling

- Electrochemical reactions

How to define species model in Ansys ? 

To model species transport and finite-rate chemistry in Ansys Fluent, you need to follow these steps:

- Enable the **Species Transport** model in the **Species Model** dialog box. You can also choose the **Non-Premixed Combustion** model if you want to simulate turbulent reacting flow using the non-premixed combustion model¹.

- Define the **species** that are involved in your problem. You can add or remove species from the list of available species in the **Boundary Species** section of the **Species Model** dialog box¹.

- Define the **reactions** that occur in your problem. You can choose from different reaction mechanisms and rate formulations in the **Reactions** section of the **Species Model** dialog box¹. You can also specify the **reaction zones**, where the reactions take place, and the **reaction orders**, which determine how the reaction rates depend on the species concentrations².

- Define the **boundary conditions** for your problem. You can specify the **species mass fractions**, **temperature**, and **reaction rates** at the inlet, outlet, wall, or other boundaries².

- Initialize and run the calculation. You can monitor the **species mass fractions**, **temperature**, and **reaction rates** during the solution process².

What are differences between species model and Euler model in Ansys Fluent

The species model and the Euler model are two different approaches for modeling multiphase flows in Ansys Fluent. The species model is used to model the mixing and transport of chemical species by solving conservation equations describing convection, diffusion, and reaction sources for each component species³. The Euler model is used to model the interpenetrating continua of different phases by solving a set of momentum and continuity equations for each phase².

Some of the differences between the species model and the Euler model are:

- The species model is suitable for non-reacting or reacting flows, with reactions occurring in the bulk phase, on wall or particle surfaces, or in the porous region³. The Euler model is suitable for granular (fluid-solid) flows or nongranular (fluid-fluid) flows, with coupling achieved through the pressure and interphase exchange coefficients².

- The species model shares a single set of momentum equations by the fluids, and tracks the volume fraction of each of the fluids in each computational cell³. The Euler model solves a separate set of momentum equations for each phase, and accounts for the phasic volume fractions that sum up to one².

- The species model requires the definition of species, reactions, reaction zones, and reaction orders³. The Euler model requires the definition of interphase drag, lift, wall lubrication, turbulent dispersion, and virtual mass forces².

💥 #12steps tutorial Ansys Design Modeler How to create plane, patterns and substract volumes 🧐

 A plane in ANSYS Design Modeler is a flat surface that can be used to create sketches or other geometry features. There are different ways to create a plane in ANSYS Design Modeler, depending on the reference geometry and the orientation of the plane.

Some of the methods to create a plane are:

• From Plane: This method creates a new plane by offsetting or rotating an existing plane. You can specify the distance and angle of the transformation, or use the drag handles to adjust the position and orientation of the new plane.
• From Face: This method creates a new plane that is parallel to an existing face of a solid or surface body. You can specify the offset distance from the face, or use the drag handle to move the new plane.
• From Centroid: This method creates a new plane that passes through the centroid of a selected body, edge, or vertex. You can specify the normal direction of the plane, or use the drag handles to rotate the plane.
• From Circle/Ellipse: This method creates a new plane that is tangent to a selected circle or ellipse. You can specify the offset distance from the circle or ellipse, or use the drag handle to move the new plane.
• From Point and Edge: This method creates a new plane that passes through a selected point and is parallel to a selected edge. You can use the drag handles to rotate or move the new plane.
• From Point and Normal: This method creates a new plane that passes through a selected point and has a specified normal direction. You can enter the normal vector components, or use the drag handles to rotate the plane.
• From Three Points: This method creates a new plane that passes through three selected points. The points can be vertices, sketch points, or points on edges or faces.
• From Coordinates: This method creates a new plane that has a specified origin and normal direction. You can enter the coordinates of the origin and the normal vector components, or use the drag handles to adjust the position and orientation of the new plane.

To create a plane using any of these methods, you need to follow these steps:

1. Open ANSYS Design Modeler and create or import your geometry.
2. In the Tree Outline, right-click on XYPlane, YZPlane, or ZXPlane and select Insert > Plane.
3. In the Details View, select the method you want to use from the Type drop-down list.
4. Select the reference geometry (plane, face, edge, vertex, point, circle, ellipse) as required by the method.
5. Specify the parameters (distance, angle, normal vector) as required by the method, or use the drag handles to adjust the position and orientation of the new plane.
6. Click Generate to create the new plane.
