AbstractIn this article, a comparative study of different drying techniques, namely, open sun drying (OSD), desiccant drying, solar drying (SD), and solar drying with desiccant (SDWD) was done for drying potato and ginger. The thermal efficiency and air temperature differences of the solar dryer based on evacuated tube collectors were also examined. The average efficiency of the solar dryer was 29.01%. Average drying rates of OSD, desiccant drying, SD, and SDWD bed are 0.435, 0.435, 0.59, and 0.635 g/min. The moisture content of the potato was reduced from 79.6% to 32.9% by OSD, 32.6% by desiccant drying, 9.6% by SD, and 6.9% by SDWD. The moisture content of the ginger was reduced from its initial value of 82.3%–25.3% by OSD, 25% by desiccant drying, 10.1% by SD, and 3.2% by SDWD. SD assisted with a desiccant bed proved to be the best method for drying vegetables. Drying with desiccants is not feasible for drying in winter and spring seasons of the Indian climate.

Fabrication of portable solar thermal bank for indoor cooking

AbstractThe aim of this report is to build a portable solar thermal bank based on a Scheffler reflector that is capable of boiling‐type cooking using HITEC as a thermal storage material. This report reviews the problems related to solar cooking and evaluates the novel layout of a portable solar thermal bank which includes a daily thermal storage vessel. This stove is in the shape of a cylindrical container filled with phase‐changing latent heat storage material. Inside the container, we provide a small gap taking into account the volumetric expansion of the phase change material (PCM) during the melting process. The solar thermal bank is charged in the sun. It is placed directly for a few hours under the focus of a Scheffler reflector, which charges the solar thermal bank with enough thermal energy stored. After a while, the cooking process can be completed by users using that stored heat. The top cavity is used as a cooking pot in a solar thermal bank. Cooking meals do not require direct sunlight, which is typical for most solar cookers. The portable solar thermal bank is an alternative for low‐income households and adapts to local traditions of indoor cooking. It is portable and can be used safely to cook indoors or outdoors. In this study, a solar cooker with a thermal storage device was developed using a PCM. The size of the stove has been calculated by calculating the energy consumption for two to three people. HITEC salt has been chosen as a phase change material for thermal storage, which will be used for cooking when there is no sunlight. It enhances the applicability of solar cooking and preserves cooking possibilities using energy stored throughout the day at low production costs.

Indian residents now have an opportunity to obtain information that is kept in government offices thanks to the Right to Information (RTI) Act of 2005. The RTI query-log data, which records citizen interactions with the government, is available in every government office. The goal of this work is to analyses the RTI query-log data in order to find fundamental latent patterns, with the hope that these patterns may provide insight into prospective legislative changes. We gather RTI queries and reply-statistics from government educational institutions all throughout India for the first time. Three latent patterns are quantified: I the organizations' transparency as determined by RTI queries stats; (ii) the influences on organizations’ accessibility; and (iii) the success of the RTI law's execution. There is a suggestion for this double institute-query-category matrix representation of the RTI data. By employing an Evaluated Response Model to estimate the data matrix's maximum probability, the aforementioned three latent parameters are simultaneously measured. We find contradictions in the RTI legislation's application through the latent patterns that were identified, while also providing recommendations for possible RTI act reform.

ABSTRACT The present paper deals with the economic investigation of hot water generation from melting of ice through Scheffler solar concentrator at high altitude regions like Leh Ladakh in India. For determination of the cost incurred per litre in terms of the Indian Currency, several factors have been studied and evaluated. In all three examined cases, for every respective case, the undeviating technique is adopted. The experimentation is performed in the atmospheric conditions of National Institute of Technology, Kurukshetra, Haryana, India. Exclusive economics of yearly cost per litre is achieved for the generation of hot water from ice at high altitudes by making use of direct heating process.

ABSTRACT In this paper, a working setup of Scheffler solar concentrator (SSC) for the steam generation application has been investigated experimentally. An experimental setup of SSC having an aperture area of 1.54 m2 and steam boiler (or receiver) area of 0.0324 m2 was set up and tested for steam generation. The steam boiler 1, 2 and 3 with different arrangements were used for steam generation. During sunshine hours, the steam boiler 1, 2 and 3 are placed at the focus of SSC at 11:00 hour up to 2.1 bar (gauge) reached. The dryness fraction of the steam boiler 1, 2 and 3 have been calculated as 43.51%, 71.61%, 96.32% and the thermal efficiency 18.40%, 14.53% and 14.09%, respectively. In all the steam boiler arrangements, it has been found that in the steam boiler 3 produced a high quality of steam.

Experimental investigation of ice-chamber for melting of ice based on Scheffler solar concentrator for high altitude regions
Himanshu Agrawal and Avadhesh Yadav
Wiley
AbstractThis experimental analysis was performed with the aim to melt the ice into hot water at very high altitude regions such as Leh Ladakh. Three different designs of ice‐chamber were used to melt the ice with direct heating in minimum time. The radiations were focused on the receiver with the help of 1 m2 Scheffler solar concentrator exposed to the atmospheric situations of NIT Kurukshetra. The Scheffler solar concentrator was fabricated with fiber‐reinforced plastic material. The fabrication process is discussed in detail. The results obtained from the design showed that the ice frozen at −5°C completely melted, converting into water. The maximum temperature of water attained in the ice‐chamber with receiver 1 (circular plate with fins), 2 (CPC with fins), and 3 (copper crucible) was 57.7°C, 64.3°C, and 67.4°C, respectively.

Abstract This paper presents an investigation of thermal performance of phase change material (PCM) in combination with different sensible heat storage materials (SHSMs) in a solar cooker based on parabolic dish collector for evening cooking. In the experimental set-up, a pressure cooker is placed at the centre of two concentric pots containing PCM in the inner pot and different SHSMs in the outer pot. During sunshine hours, this unit (solar cooker) is placed on a plate of parabolic dish collector for storing the thermal energy in the SHSMs. In the evening, the solar cooker is kept in an insulator box and loaded with cooking food, where the PCM deliver heat to the food. It has been found that PCM-Sand and PCM-Stone pebble cases store 3 to 3.5 times more heat as compared to PCM-Iron grits and PCM-Iron ball cases. The PCM assists in cooking while the outer material assists PCM in maintain its performance.
