Which solar chimney configuration is best for power generation?

Comparing simulation results revealed that a divergent solar chimney configuration which has the largest H d / R in is the best option for power generation, the DISC is second-best option and the DOSC is the last. They also proposed a controlled approach for the design of a solar chimney containing a variable diffuser outlet.

What is a solar chimney power plant (SCPP)?

Solar chimney power plant (SCPP) uses solar energy to hit the ambient air which when allowed to pass through a chimney runs a wind turbine that in turn runs a generator to produce electricity.

Does a focused airflow increase power generation in a solar chimney?

The result of their CFD analysis in large-scale plants revealed that a focused airflow in the throat increased power generation and the flow speed throughout the chimney, but especially at the bottom – a precept which was further studied on an indoor scale solar chimney.

How does a chimney design affect the performance of solar power plants?

The design parameters affect the performance of solar chimney power plants as much as the geometric parameters. This situation was understood from the slope of the collector. Similarly, the chimney design affects the performance of the system.

How a solar chimney power plant works?

There is a turbine in the chimney at a certain height from the ground. The kinetic energy of the system’s air hitting the turbine blades is converted into electrical energy, and power output is obtained from the system. The simplified mechanism of the system is given in Figure 1. Figure 1. Solar chimney power plant scheme. 3.

Are solar chimney power plants a reliable source of renewable electricity?
