The solar chimney power plant (SCPP) is a hopeful solution to produce electrical power from solar energy. In this paper, a 2D numerical study is presented to estimate the performance of the SCPPs while varying the collector angle, chimney diverging angle, variable solar radiation and ambient temperature and some geometrical designs. Numerical models run with solar load discrete ordinates (DO) and realizable k-ɛ turbulence models. System is defined by the collector height =50 mm, the chimney diameter =160 mm, the collector diameter =2750 mm and the chimney height =3000 mm. its investigated for each case the profile of magnitude velocity, air temperature, pressure, incident radiation and turbulence characteristics were presented. The effective choice of the best geometry is based on the maximum value of the air velocity inside the SCPP. Results indicates that a negative collector-roof positively increases the air velocity, and the output power. To a specific limit, increasing the diverging angle of the chimney has a god effect on the velocity magnitude and the other parameters. also Increasing the collector diameter and chimney height and diameter has a great effect on power output as shown in results.

“…This study was assumed that solar chimney would be generated power of 0.07 Watts. Aurybi et al (2018) explained that an electrical power was affected by turbine efficiency (80%) and generator efficiency (95%) of maximum turbine power. Therefore it was important to identify the losses power that causes of efficiency decreased.…”

The Solar Chimney Power Plant (SCPP) is an energy conversion system that would absorb solar thermal energy and convert heat air into electrical energy using a collector. The main disadvantage of the SCPP is that low efficiency because less solar heat flux can be converted to the electrical power affected by the design of the SCPP. This study was designed the SCPP by theoretical calculation for producing electrical power and experimented by designing the SCPP use a chimney with divergent shape, a collector with convergent shape, a turbine generator with 3 blades, and coating some materials at the collector’s ground to increasing the electrical power. The purpose of this work was to study about the impact of the solar heat flux ( ) to the temperature of air, to the velocity of air, to the power electricity and compare between power generated from theoretical calculations design and the experiments result. The result showed that the SCPP with the optimized design affect the performance of the SCPP’s output power. The power generated in this experiment is 0.1 Watt. That value is greater than output power from theoretical calculations about 42.8% for the same input solar heat flux ( ) 1118 W/m2 both for theoritical and experimental.

“…Papageorgiou [16] introduced the concept of the floating chimney made with fabric that is costeffective and safe during an earthquake, however, crosswinds can deflect the chimney affecting the chimney performance. Aurybi et al, [2] propose a solar chimney integrated with a thermal power plant, it uses the hot waste flue gas as a heat source to operate the solar chimney during night time or at low solar radiation intensity [2]. Hu and Leung [9] and Hu et al, [10] performed numerical solution on cylindrical, divergent and various shape of diffuser chimney.…”

Solar chimney power plant is a sustainable alternative for electricity generation using solar as the source of energy. In general, the main body of a solar chimney plant requires a tall structure which is costly and challenging to construct. Thus, it is important to increase the performance of the solar chimney power plant and have a better energy-cost ratio. This study aims to experimentally investigate the influence of divergent solar chimney as opposed to a cylindrical chimney on solar chimney performance. Three divergent scaled-down solar chimney model at 1-meter, 1.5-meter and 2-meter were fabricated and tested for its performance at various simulated heat loads. The test results were compared with similar heights cylindrical solar chimney. The experiments show that divergent solar chimney increases the theoretical power generation potential and improves the stalk effect and have higher outlet velocity compared to a cylindrical solar chimney. The power potential of the divergent chimney is increased up to 18 times with the maximum theoretical power obtain at 0.183W on the 2-meter divergent chimney. Higher temperature was recorded on the 2-meter divergent chimney outlet at 341.3k compared to 330.4k on the cylindrical chimney indicates better stack effect. The highest average velocities in the divergent and cylindrical chimneys were recorded under the electric heat load of 2 kW at 0.994 m/s and 0.820 m/s respectively in the 1-meter configuration. It is also observed that the air velocity in a shorter divergent chimney is higher than taller divergent chimney models while better compared to all cylindrical height. This study finds that a shorter divergent solar chimney produces greater energy compared to a higher cylindrical solar chimney. Therefore, it is possible to reduce the overall cost of solar chimney by reducing the height of the main structure without sacrificing the performance of the solar chimney.
