Solar chimneys (or solar updraft towers) offer an attractive way to use solar energy for production of baseload power. In a power plant of this type, sunshine heats the air under a wide greenhouse-like roofed collector surrounding the central base of a tall chimney. The heated air drives an updraft flow through the tower, whose energy is harvested with turbines. For a sufficiently large plant of this type, the thermal mass of the heated ground under the collector is sufficient to drive the flow even when the sun is down. The primary challenge in building the solar chimney power plant …

The aim of this investigation is to verify and validate the modeling of fluid mechanics and heat transfer processes in a solar chimney power plant. The modeling uses a finite volume method applied to simulate the fluid flow and solve Navier-Stokes equations for the two- dimensional models of the plant. The representative size of the plant can be very large, and turbulence must be accounted for. Several turbulence models were applied in the model. The upstream velocity and power generated by the power plant system was calculated from the CFD results and compared with experimental results and available …
