Summary
Proposes an annular tower design for a divergent solar chimney power plant, aimed at avoiding boundary layer separation when the tower widens. 3D simulations based on the Spanish prototype vary the outer and inner tower radii. Performance turns out to be highly sensitive to both radii, and the best configuration raises power output by about 32%. A lower-cost variant that balances cost against performance is also suggested.
