In this study an appropriate expression to estimate the output power of solar chimney power plant systems (SCPPS) was considered. Recently several mathematical models of SCPPS were derived, studied for a variety of boundary conditions, and compared against CFD calculations. An important concern for modeling SCPPS is the accuracy of the derived pressure drop and output power equation. To elucidate the matter, axisymmetric CFD analysis was performed to model the solar chimney power plant and calculate the output power for different available solar radiation. Both analytical and numerical results were compared against the available experimental data from the historical Manzanares …

Rather than dumping the waste heat rejected by a nuclear power plant to a wet cooling tower, a better solution may be to connect it to a solar chimney power plant system (SCPPS). This is particularly true in arid regions. The SCPPS serves the function of a dry cooling tower but also produces additional electrical power. In a solar chimney power plant, the energy of buoyant hot air is converted to electrical energy. This solar power plant includes a collector at ground level, covered with a transparent roof that collects the solar radiation, heating the air inside and the ground …
