Abstract: All major developing nations have started to invest in renewable energy to promote a cost-effective and low emission way of power production. Policy planning and financial aspects are the key issues for renewable power development. Comparing two major developing countries, Iran and India, would provide a deeper understanding of the future trends and policy scenarios related to renewable energy. This paper provides a review of the governance structure, current renewable energy policies, legislation, economic policies, and incentives that would analyze the renewable energy development in both countries. The final section of the paper discusses the current status of renewable energy generation in both countries followed by comparative policy analysis. The results concluded from the paper are that India shows a much stronger commitment towards renewable energy with a higher percentage of generation, well-structured governance, and independent ministry which presides over the whole sector. Iran although new to the industry shows a lot of promise with better feed-in tariffs and an open market for independent investors and producers. The paper suggests lesser investment interest rates, better technical expertise, and incentives for off-grid producers for India while a more developed legislative structure for Iran along with the formation of subordinate research organizations.

Abstract: In this paper water vapor is directly generate in a short circuit by means of a compound parabolic trough concentrator (CPC) while optimizing the manufacturing costs of the solar device used. Direct steam generation has been widely studied, especially for high power systems. However, experimental applications for small solar field areas are rare, especially for concentrating solar technology. This research shows that it is possible to produce water vapor with a CPC for cooking, dry cleaning, maintenance and cleaning, etc. The different heat exchanges that took place in each compartment of the CPC were described. The heat transfer equations were solved by the Gauss-Seidel’s method. An advanced difference scheme is used for the storage terms and a decentered scheme for the transport terms. The numerical simulation has been implemented by matlab code. The different CPC parameters have been directly measure experimentally. The results show that for a CPC length Lc=1 meter and width lc=50 centimeter, the theoretical temperatures of the water and the absorber can reach 125°C and 150°C respectively, while the experimental temperatures of the water and the absorber are 108°C and 112°C respectively. The temperature of the water vapor measured can reach 110°C. The mass of water vapor produced with this device is 0.110 Kg with a mass flow rate of 3x10-6 Kg/s and a saturating vapor pressure of 1.05 bar. The theoretical thermal efficiency reached is 52% against an experimental value of 35% for a global solar radiation of 950 W/m2 and an ambient temperature of 43°C at solar noon in April 2021. The CPC is designed to operate only during the day, and we are planning to add a heat storage system to our CPC for night use of the steam produced. In addition, instead of water, we can test the CPC's operation in the future with vegetable oils such as moringa oil.

Abstract: The low thermal conductivity of phase-change materials (PCMs) hampers the commercialization of PCM cooling battery thermal management systems. Further reduction of the thermal resistance between the PCM and batteries is still a challenging problem. In this study, a PCM / pin fin design is proposed. ANSYS Fluent was used to construct the model of PCM / pin fin design. The SIMPLE algorithm and the second-order upwind scheme were used to solve the momentum and energy equations. Compared with the traditional pure PCM and PCM/plate fin designs, the maximum temperature of the battery (Tmax) was lower for the PCM/pin fin design because the heat transport from the batteries to the PCM was enhanced owing to the pin fin with a larger heat-transfer area. Tmax for the pure PCM configuration reached 55.76°C after discharge, exceeding the upper-limit temperature of 55°C. In contrast, for the PCM/pin fin design, Tmax was only 53.44°C. This indicates that the PCM/pin fin design effectively alleviates the heat accumulation of the battery and successfully maintains the battery temperature within a safe range. The effects of PCM thickness and fin section area on thermal behavior were investigated. It was found that the decrease of fin cross-sectional area can significantly reduce Tmax. When the fin cross-sectional area is 1 mm2, the Tmax is only 51.07°C. In addition to control Tmax under 55°C, the minimum PCM thicknesses were 3.71, 2.89, and 2.38 mm for pure PCM, PCM/plate fin, and PCM/pin fin, respectively. Thus, compared with the other designs, in the PCM/pin fin design, fewer materials are required, the weight of the modules is reduced, and the energy density is improved.
