Improving Electricity Production in Solar Chimney Power Plants with Sloping Ground Design: An Extensive CFD Research

“…When the Manzanares pilot plant and other installed power plants are examined, it is seen that the air temperature in the system does not change much [5,[8][9][10][11]. Researchers claim that the Boussinesq model can be used for density analysis in systems where the temperature change is not very large [1, 6,12,41,44,45]. Its equation is as follows:…”

“…Different calculation methods are available in literature for determining power output of SCPP systems. The generally accepted calculation method is to calculate the power from the pressure drop (∆ ) in the turbine [1, 6,12]. The power output of the system is calculated from the following equation: [12,13].…”

“…In the equation, is the turbine-generator efficiency and taken as 0.8 [1, 6,12]. It is seen that the power output of the system is proportional to the pressure drop (∆ ) in the turbine and the volumetric flow rate ( ).…”

“…It is measured that the system gives a maximum power output of 50 kW at a solar intensity of 1000 W/m 2 [5]. Although the Manzanares prototype did not continue its operation in the following years, it has pioneered many studies to increase the performance of SCPP systems with mathematical, theoretical and CFD models developed in the light of experimental measurements [6]. Mullet [7] claimed that the efficiency of the system at 1000 m chimney height for large-scale systems will exceed 1%.…”
