And the controller has to be designed with modulation technique, for both voltage and current at particular frequency following stabilization which is both simple in implementation and operation. And the comparative analysis of techniques used has to be carried out with AI-based optimization algorithms for studying its effectiveness. The results of the THD % of voltage in the system having no controller was found to be 3.32 %.&nbsp; in the system having adaptive neural PSO switching of grid dynamics controller, the distortion level came down to 1.96%. The hybrid system with solar wind energy was further integrated with the grid and was analyzed for the rotor angle stability in the two machines. It was concluded that out of the three controls for grid dynamics controller the artificial intelligence-based adaptive neural PSO switching was found to be best with maximum stability of machines.</strong></p> Syed Sanjar Ul Islam, Santosh kumar Copyright (c) 2020 https://creativecommons.org/licenses/by/4.0 https://ijoscience.com/ojsscience/index.php/ojsscience/article/view/312 Sat, 12 Sep 2020 00:00:00 +0000 Optimizing Thermal Behavior of Flat Plate Heat Exchanger Tube by Varying Geometrical Configuration https://ijoscience.com/ojsscience/index.php/ojsscience/article/view/313 <p><strong>A plate fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between liquids. It is often classified as a compact heat exchanger to emphasize the relatively high ratio between the heat transfer surface and the volume. The main objective of the present work is to investigation of optimum design of plate fin tube heat exchanger using Computational fluid dynamic approach and maximizing thermal performance. There are total five designs of plate fin and tube heat exchanger are used in present work and CFD analysis have been performed in it to get maximum heat transfer. It has been observed from CFD analysis that the maximum heat transfer can be achieved from plate fin and tube heat exchanger with elliptical tube arrangement inclined at 30<sup>o</sup> with 23.22% more heat transfer capacity as compared to circular tube plate pin heat exchanger. So that it is recommended that if the plate fins and tube heat exchanger with inclined elliptical tube used in place of circular tube arrangement, batter heat transfer can be achieved. </strong></p> Nitesh Kumar Singh , N.

In recent years, grid stability problems have been detected due to the rapid growth of electrical and electronic loads. To study the system performance under the effect renewable energy based generating units the kundur’s two area system has been taken as test system. The direct integration of these resources were studied for various instability issues like rotor angle stability, power stability at the generating points of machines and distortion level in the voltage and current waveforms of the grid system. The work has proposed a universal dynamic system optimizing control for system stability enhancement in all the aspects. The MATLAB/SIMULINK environment being the platform for the system designing and implementation, The effects on the two area four machines system has been studied by integrating wind energy system without dynamics optimization control in area 1and then systems with both solar and wind with the dynamic optimization controller at area 2 was developed. The study is further carried to integration of a fuel cell system in area 1 as well. The rotor angle stability and power stability at the point of generation bus was also stabilized by the proposed control in the power system.</strong></p> Pramod Kumar Meher , Mrs. Madhu Upadhyay Copyright (c) 2020 Pramod Kumar Meher , Mrs. Madhu Upadhyay https://creativecommons.org/licenses/by/4.0 https://ijoscience.com/ojsscience/index.php/ojsscience/article/view/314 Thu, 20 Aug 2020 00:00:00 +0000
