Investigation of Electric Field Distribution of A Transformer Using Moving Finite Element Method

[Mehmet ÇINARİrfan ÖKTEN] Volume 5: Issue 2, June 2018, pp 36-43 

DOI: 10.26706/IJAEFEA.2.5.20180602

Abstract - The one of the commonly used methods for solution of partial differential equations is the finite element method. Solution area for the differential equation to be solved in this method; are divided into a number of sub-regions called simple , small , interconnected , finite elements.However , especially in time-dependent partial differential equations, analysis is performed using the moving finite element method instead of the classical finite element method where the solution network changes locally; both faster and more accurate.In this work, moving finite element method is considered. The details of how the original variation on the solution network for he moving finite element method and the monitor function selection, which is an important factor in these changes, are detailed in the two-dimensional case. As application, C ++ based software is implemented and analyzed the transformer’s electric area distribution according to the state of the classical and moving finite elements and the results are compared.

Performance evaluation of forced convection desiccant bed solar dryer integrated with sensible heat storage material

[Pramod V. WalkePranav C. PhadkeKishor S. Rambhad] Volume 5: Issue 2, June 2018, pp 24-35 

DOI: 10.26706/IJAEFEA.2.5.20180501


Abstract This paper reports a new type of forced convection indirect type solar dryer setup fabricated in Nagpur, India and its performance was studied. The main objective of the present study was to incorporate new drying technology and develop a solar dryer that could function effectively for few more extra hours even after the sunset. Thus a forced convection indirect type solar dryer integrated with heat storage material (Gravel) & desiccant beds (Silica Gel) was developed.

In forced convection solar dryer with heat storage material, the grapes were dried from an initial moisture content of 80% to the final moisture content of 20%  in about 78 hours, while it took only about 57 hours in the forced convection solar dryer with heat storage and desiccant beds to reach the required moisture content. Due to the use of heat storage material, the temperatures inside the solar dryer remains 3-5°C higher than the ambient temperature even during off sunshine hours. Also, the heat storage regulates the temperature of the collector outlet during uneven climatic conditions. The maximum temperature attainedby air inside the dryer cabinet was 78°C. The desiccant beds can be regenerated in about 5 hours during a normal day and removes the moisture from the products even during the night. The air flow rate in both the cases was maintained at 0.026 kg/s. The quality of the grapes obtained from the solar dryer was excellent with proper coloring and taste as compared to those dried directly under the sun.

A Review on Productivity and Quality Improvement through Optimization of Input Parameters in the Indian Rolling Mills

[Amit Bankar, Hemant Bansod, Vijay Kalbande, Pankaj Jaiswal] Volume 5: Issue 1, March 2018, pp 18-23

DOI: 10.26706/IJAEFEA.1.5.20180302
Abstract - India has risen as the fourth biggest steel delivering country on the planet, according to the current figures discharge by World Steel Relationship in April 2011. The Indian steel industry represented around 5% of the world's aggregate generation in 2010. Steel re-rolling is a standout amongst the most essential portions of the steel business, as it constitutes an unavoidable connection in the aggregate inventory network of iron and steel. The auxiliary steel creation constitutes around 57% of the aggregate steel generation in India. It essentially happens in steel re-moving factories (SRRM) that as a rule are family-run little and medium undertakings (SMEs) with 75% of units in the little scale. The steel business in India is one where supervisors appear to firmly have confidence in the customary method for working together, which could bring protection against any new quality change device like lean and six-sigma. This paper manages the investigation of the Indian moving plant and the impact of the different information parameters on the profitability and quality.
