Variable air calculates the viscosity and conductivity. The only time variable air is really needed is in a compressible analysis that the viscosity and conductivity is expected to change. To better understand what "Variable" vs "Fixed" means, here is a screen shot of the material environment for variable air:

The second variable that you should check when using wall functions is the wall liftoff (in length units). This variable is related to the assumed thickness of the viscous layer and should be small relative to the surrounding dimensions of the geometry. If it is not, then you should refine the mesh in these regions as well.

A transport equation is any differential equation for any variable that we solve in CFD. But don’t assume one interpretation of the phrase. The term “transport equation” conjures several different levels of expression in CFD. Two engineers are communicating. They use a “transport equation” as loose math, emphasizing the derivatives of ...

discrete variables In a CFD solution, one would directly solve for the relevant ﬂow variables only at the grid points. The values at other locations are determined by interpolating the values at the grid points. The governing partial diﬀerential equations and boundary conditions are deﬁned in terms of the continuous variables p, V~ etc ...

: when an extension transfers a call to a CFD app, this variable contains the extension number that transferred the call. Call Flow Components. The available built-in components related to variable management and call flow path execution, can be configured via the “Properties” panel, or by double-clicking the component to open its configuration dialog.

Computational Fluid Dynamics (CFD) computations (Ref. 9) of a blade in a linear cascade under large negative angles also exhibited vortical structures aligned in the spanwise direction on the pressure-side cove. Since the test blade was a linear cascade, the vortex realigned itself to flow direction near the midspan of the linear blade.

A "conserved" variable in this context is actually a conserved quantity per unit volume - density, density times velocity, density times specific energy. The primitive variables are density, velocity, temperature etc. The textbook NS equations are usually formulated in the primitive form. At the analytical level the two are exactly equivalent ...

A 20-level DOE study is carried out using the Optimal Latin Hypercube method for the above design variables, and the CFD simulations are conducted and 20 sets of response values are obtained, as shown in Table 5. The 20 levels of each design variable are divided between the lower and upper bounds of the design space.

First, the best values of cant and sweep angles in terms of aerodynamic performance were selected by performing simulations. The analysis included cant angle values of 30°, 40°, 45°, 55°, 60°, 70° and 75°, while for the sweep angles 35°, 45°, 55°, 65° and 75° angles were used. The aerodynamic performance was measured in terms of the ...
