“…Implementation of the uncertainty analysis is necessary in order to investigate the reliability of the results. The total uncertainty for a measured parameter (P) can be calculated using the following equation (Zamani et al, 2015;Hosseinzadeh et al, 2020): Some measured parameters are shown in Table 5.…”

Energy need for cooking in both the rural and urban areas all over the world is increasing every day as a result of an increase in population. The consequence of global warming due to the usage of fuels such as fossil fuel, firewood, and other biomass products for cooking necessitates innovative techniques that will improve the standard of living of people. In this study, the design, fabrication, and thermal evaluation of a solar cooking system integrated with an Arduino-based tracking device and sensible heat storage (SHS) materials was investigated. During the water boiling trials with black oil sensible material (BOSHSM), the obtained maximum temperatures for water, cooking box, and sensible heat storage material at 14:00 h when the solar radiation attained its peak value of 881.2 W/m2 were 64,52, and 54°C, respectively, while at 14:00 h with Black coated granite sensible heat storage material (BCGSHSM) at the solar radiation peak value of 890.4 W/m2, the maximum temperatures for water, cooking box, and sensible heat storage material were 73.5, 76, and 59°C, respectively. The maximum cooking power and thermal efficiency obtained from the water boiling trials were 48.4 and 56.4 W, and 31.6 and 35.8% respectively. Also, the results from the cooking of edibles revealed that the cooking power values ranged between 42.5 and 58.2, while that of efficiency ranged between 34.5 and 40.3% respectively. The maximum solar radiation during the cooking trial period was 986, 975, 956, and 953 W/m2. In general, from the results, the developed solar cooking system is a viable alternative to cooking with traditional/open burning of wood or other biomass products that pose a serious environmental and health-related threat to the people living in developing countries.

Increased energy demand has forced societies to rely on traditional fuel sources with negative health and environmental impacts. In most developing countries, solar energy is available for long hours and in ranges that if exploited can reduce dependence on biomass and fossil fuels. However, despite its potential, uptake of solar cooking devices is low due to intermittent radiation, technological challenges, lack of awareness and slower cooking rates compared to other energy sources. There are four traditional types of solar cookers, box, panel, parabolic and tube. The latest technology is the PV conversion to electricity. Since the advent of solar cooking, numerous experiments, designs and improvements of solar cookers have been successfully developed. Research has focused on improving solar cooker performance such as; improved design, sun tracking mechanisms, solar thermal storage or "hybrid" designs that remove limitation of nighttime cooking or periods of poor irradiance. These improvements have increased the efficiency, reduce the cost of the solar cookers, and addressed sociocultural challenges such as sheltered cooking, visual appearance, and the ability to cook traditional recipes. However, more needs to be done to increase ease of adoption, the capacity of energy storage and flexibility. The cost of domestic workloads and environmental degradation should also be a factor in energy policy formulation.

“…In this methodology, all factors are simultaneously varied between minimum and maximum values. It is worth quoting that RSM has been applied successfully in various scientific and technical fields ( Cojocaru et al, 2009a, Cojocaru et al, 2009b, Kacan, 2015, Khayet et al, 2007, Khayet et al, 2010a, Khayet et al, 2010b, Khayet et al, 2011a, Schenone et al, 2015, Zamani et al, 2015and Ai et al, 2015. In the present study, the central composite experimental design (CCD) and RSM has been applied to model and optimize a solar FO pilot plant.…”

Modeling and optimization of a solar forward osmosis pilot plant by response surface methodology

Forward osmosis (FO) is a water treatment/separation technology of emerging interest. Due to its complex nature involving various operating parameters, modeling of this separation process is challenging. A solar thermal and photovoltaic-powered FO pilot plant has been optimized by means of a statistical experimental design and response surface methodology. Predictive models were developed for simulation and optimization of different responses such as the water permeate flux, the reverse solute permeate flux and the FO specific performance index that includes the water and reverse solute permeate fluxes together with the energy consumption. The considered input variables of the FO pilot plant were the feed flow rate, the permeate flow rate and the temperature. The developed response models have been tested using the analysis of variance. A Monte Carlo Simulation method has been conducted to determine the optimum operating conditions of the FO pilot plant. The obtained optimum parameters were confirmed experimentally. Regeneration of the draw solution can be performed by means of an optimized solar powered reverse osmosis (RO) pilot plant with an optimum FO specific performance index ranging from 25.79 to 0.62 L/g kW h achieved under the FO optimal conditions, 0.83 L/min feed flow rate, 0.31 L/min draw solution flow rate and 32.65 °C temperature. The FO energy consumption is only 14.1% the total energy consumption of the FO/RO hybrid system.
