Popis:	Three different models were developed to examine the flow and thermodynamic characteristics of the solar updraft tower (SUT) power plant and the best model is proposed. A step is taken to find the location of the turbine to absorb maximum kinetic energy. It is found that the maximum and average air velocities inside model-I were higher (3.06 and 1.63 ms−1, respectively) compared to model–II (2.4 and 1.34 ms−1) and model-III (2.9 and 1.57 ms−1). The maximum air temperature inside the model-II was higher (322 K). Turbulent kinetic energy, power produced and overall efficiency were the best in model–II than the other two models. The present outcomes were validated with the literature data and observed a good match.
