This paper presents a two-dimensional numerical analysis of a solar chimney integrated with an absorbent wall on the south façade of a building. The investigation was carried out in July and December in Aversa, Italy, from sunrise to dusk. The solar chimney features a converging channel, a vertical absorbing wall, and a glass plate slanted at two degrees. A thermal energy storage system comprising phase change material and metal foam behind the absorbing wall was evaluated. Using Ansys-Fluent, four configurations were analyzed to identify the optimal layout for thermal performance. Key findings include liquid fraction, energy stora...

Building thermal comfort using the passive cooling method is an air conditioning process using natural methods without using electricity tools. The solar chimney-earth air heat exchanger (SCEAHE) system uses passive cooling techniques to provide thermal comfort in buildings. It utilizes renewable energy in the form of solar and geothermal energy. This system not only reduces electricity consumption but also has the potential to minimize fossil fuel utilization and create green technology. This paper presents a review of SCEAHE system integration for thermal comfort building from previous research and finds a prospective goal for its...

A new energy generation system combining a solar chimney power plant (SCPP) with a nuclear power plant (NPP) cooling tower has been developed and assessed in Irbid, Jordan. The surplus hot air from the NPP is directly routed into the SCPP collector, increasing the initial air temperature and boosting the air profile of the SCPP, improving the air velocity inside the chimney and boosting electricity and water production. The integration of these two systems (SCPP+NPP) has shown significant improvements in electricity and water production compared to a standalone SCPP. The integrated system provides reliable electricity production thr...

A solar chimney is a one source used newly in power generation by converting solar energy to kinetic energy. One of the limitations of using a solar chimney is the availability of large areas for building the chimney system to obtain sufficient kinetic energy at the chimney entrance. Addressing spatial constraints in chimney systems, this study pioneers an innovative approach to augment energy generation within existing footprints. By integrating swirl guide blades into the collector, the air movement path is extended, resulting in an increase in energy at the chimney entrance. Rigorous examination of four swirl guide blade configur...

In the research, an experimental model of a hybrid PV solar chimney was manufactured and installed, and it was combined with different materials. The effect of these materials on the PV/solar chimney performance was studied. Asphalt was used as a phase-change- material (PCM), and the gravel bed as a porous media. Results were taken for PV chimneys integrated and not integrated with PCM and the porous media. The results found that these materials have a good effect on the performance of solar chimneys. The experimental results were as follows: The highest values of electrical efficiency were for the chimneys combined with porous med...

In response to the ongoing quest for more efficient renewable energy sources, this research addresses a significant gap in understanding the performance variations of Solar Chimney Power Plant (SCPP) models, particularly focusing on the influence of flow parameters in full and half-inclined collector sections featuring semi-elliptical curvature. The motivation stems from the need to optimize SCPP designs for enhanced energy generation while minimizing resource utilization and environmental impact. This research focuses on investigating flow parameter variations in Solar Chimney Power Plant (SCPP) models with full and half-inclined c...

Solar chimneys represent a promising passive strategy to enhance natural ventilation and heating in buildings, contributing to reduced energy consumption and improved indoor thermal comfort. This study aims to evaluate the integration of various phase change materials (PCMs) into a solar chimney system for residential applications in Tehran, Iran, and to identify optimal configurations for energy-efficient operation. Four PCMs with distinct melting points—RT10, RT21, RT35, and RT42—were assessed for their ability to stabilize indoor temperature and reduce heating demands. A transient numerical model, developed in C++, simulated ...

Building Integrated Photovoltaic (BIPV) cladding is used to enhance the thermal performance of building envelopes, thereby reducing energy needed for heating and cooling. BIPV cladding functions both as a protective layer against direct sunlight during the summer and as a system to preheat the air during winter through a naturally ventilated setup. Numerous studies demonstrate the potential energy savings associated with a BIPV envelope system. However, most of them have been conducted in virtual environment, highlighting the need for more real-world validation. This work focuses on designing and implementing an experimental setup i...

This paper explores the use of Solar Chimney Power Plants (SCPPs) for the production of green hydrogen as a means to store excess electrical energy generated from renewable energy resources (RESs). The proposed structure produces electrical energy and distilled water by heating the air under the SCPP. The electrolyzer is integrated into the seawater pool and installed at the solar chimney's base. The weather conditions at the proposed location of the SCPP including solar radiation, temperature, humidity, and wind speed, are analyzed to assess their impact on the performance of the SCPP. The potential applications and economic feasib...

The solar chimney power plant (SCPP) provides the approach to achieving carbon neutrality goals. The power generation of the system decreases drastically due to the ambient crosswinds (ACWs). In this paper, three wind resistant structures, including blockage wall, radial partition wall (RPW), and porous wall are adopted to weaken the effects of the ACWs. In addition, the flow characteristics and power generation performance of each system are investigated in the first consideration of the 3D turbine by developing a numerical model. The results reveal that the negative effects caused by the ACWs on the system are attenuated by integr...
