Numerical Models Choice and Validation with Anterior Results

This chapter reviews the methodology used to model a solar chimney using ANSYS Fluent 17.0 and the validation study to confirm the different models suitable to simulate the airflow through a solar chimney system. A 2D numerical simulation is carried out to analyze and compare the performance of different numerical models and inner details of the solar chimney by taking Kasaeian et al. (2014) as a case validation. We use geometric parameters and metrological data similar to Kasaeian et al. (2014). To validate our numerical results with his experimental results. The main objective of this chapter is to choose the numerical parameters using the CFD code to investigate the airflow in the solar chimney.
