Modeling is mainly the basis of engineering and it is a suitable simplification of
reality. The displaying expertise is to detect the fitting degree of disentanglement,
recognize significant highlights from those that are insignificant in a specific
application, and use designing judgment. This chapter presents a complete model
specification of the solar chimney power plant on which all simulations and
results are based and devoted to the presentation of the physical and numerical
models by using in the CFD code ANSYS Fluent 17.0. The following will discuss
the equations and models incorporated by ANSYS Fluent to model a solar
chimney power plant. The governing equations will be presented, which describe
the coupling of temperature fields, velocity, and pressure from the conservation
equations. Then, the discretization methods and meshing used will be examined.
Finally, the models for turbulence and radiation will be explored.
