“…It was also recommended that in the range of 0.7-0.85, the ratio of the decrease in the turbine pressure to the total pressure potential be chosen to achieve the optimal output of the SCPP. In addition, this study showed a significant rise in wind speed [24].…”

The solar chimney is one of the uninvestigated areas in the possible selection in the field of renewable solar energy utilization. CFD can be demonstrated as a useful tool of figure confidence in the design and employment of a solar chimney. A realistic numerical model for a solar-based updraft power plant for power generation was established through this research work. Iraqi weather in Kirkuk, northern Iraq was considered for this case study. A three-dimensional (3D) simulation of the main geometric dimensions of the Spanish, Manzanares model integrated with a real turbine was performed using computational fluid dynamics (CFD). The turbulent model of RNG k-e, the nongrey discrete coordinate (DO) radiation model, and the solar raytracing algorithm were used. It was observed that the air velocity below the turbine was graded according to the seasons of the year and was at its maximum in July with 18.28 m/s due to the high ambient temperature, and the lowest value was recorded in January with 8.64 m/s. The overall average daily and monthly energy production values for the Kirkuk system were higher than those of the Kubang system, with values of 310 kWh/day and 9314 kWh/month, respectively, for the Kirkuk system, and 246 kWh/day and 7398 kWh/month, respectively, for the Kubang system. The simulation results showed that the electricity generation from the Kirkuk city power plant varied seasonally to be at its maximum value of 14,424 kWh/month in July. This research work will help to determine the possibility of producing electricity in this Kirkuk city, which would then contribute in a great way to reduce the cash spent on electricity.

“…Like the chimney design, the collector is also an important parameter affecting the system. Researchers evaluate the effect of the collector with different inclination angles on the system (Hoseini and Mehdipour, 2018;Setareh, 2021;Hassan et al, 2018). It is claimed by the researchers that the collector slope increases the power output of the system but will decrease it after a point (Ahirwar and Sharma, 2019;Keshari et al, 2021).…”

In this study, based on the Manzanares prototype, a typical SCPP system is considered with a collector height of 1.85 m, a chimney with a height of 194.6 m and a diameter of 10.16 m, and a collector with a radius of 122 m. With the 3D CFD model designed in ANSYS, the impacts of the change in the collector radius and collector height on the system performance are analysed by considering the turbulence effects. The numerical results are compared with the experimental data on the power output capacity of the pilot plant at different radiant fluxes and a good agreement is obtained. Then, by taking the chimney height and diameter constant, the numerical solutions are repeated for different collector radii in the range of 52.5-175 m. The results indicate that increasing the collector area, which means increasing the energy entering the system, leads to a notable improvement in the power output of the pilot plant. With a collector radius of 175 m, a power output of 95 kW can be obtained whereas it is 55 kW in the reference case with a collector radius of 122 m. Similarly, the solutions are repeated by changing the collector height between 1.1 and 4 m while keeping the other dimensions constant. It is seen that the increase in collector height negatively affects the performance of the system. It is observed that reducing the collector height to 1.1 m for the pilot plant can increase the power output to 61.77 kW.
