Title: Numerical Analysis of Solar Flat Plate Collector for Circular Pipe Configuration by using CFD Authors: Ranjitha, P.; Somashekar, V.; Jamuna, A. B. Abstract: In this work experimentally and theoretically investigated results of flow and temperature distribution in a solar collector panel with circular tube configuration is taken and it will be compared with CFD simulated results. Fluid flow and heat transfer in the collector panel are studied by means of computational fluid dynamics. In CFD simulation ICEM CFD for modeling and CFX13 for analysis are used. Results of CFD simulation will be obtained by CFD-POST. The temperature distribution through the absorber is evaluated by means of temperature measurements at the inlet and outlet of absorber tubes. The measured temperatures are compared with the temperatures determined by the CFD analysis. Hence clearly the experimental results are validated through CFD simulations.

Title: Characterisation of Al6061-Fe2o3 Metal Matrix Composites Subjected to Severe Plastic Deformation for Multiple Passes through Equal Channel Angular Pressing Authors: Phanibhushana, M. V.; C.N., Chandrappa; H.B., Niranjan Abstract: Aluminum Metal Matrix Composites are being used widely since 3 decades in Engineering and non-Engineering applications due to their versatile properties. The properties of the composites can be enhanced by subjecting them to Severe Plastic Deformation (SPD). Equal Channel Angular Pressing (ECAP) is one of the most commonly used methods of SPD, which produces ultra-fine grains in the structure. In this work AMCs have been fabricated using Al6061 alloy as matrix material and Hematite (Fe2O3) as reinforcement. Stir casting technique has been used for the fabrication of composites by varying the composition from 0% to 4% in steps of 1%. The specimens are subjected to two passes of ECAP. The load for the deformation of the specimen has increased as the % reinforcement increased and also from first pass to the second pass. Performance of the composites before and after SPD is studied by evaluating different properties and an enhancement in the properties is observed

Title: Evaluation of Mechanical Properties of Al6061 Reinforced with Hematite Authors: Phanibhushana, M. V.; C. N., Chandrappa; H. B., Niranjan Abstract: The Metal Matrix Composites (MMCs) are being used in many engineering and structural applications in the recent years due to their high strength to weight ratios (1, 2). In the present work an attempt has been made to fabricate a new composite with Al6061 as matrix material and Hematite also known as ferrous oxide (Fe2O3) as reinforcement. The need for higher strength and higher hardness of the composite has initiated the present investigation. The Hematite reinforcement was added to Al6061in different proportions (2, 4, 6 & 8 %) by weight and composites were prepared by Liquid Metallurgy (stir casting) technique through the vortex method. The casted composite specimens were machined as per ASTM standards. The Mechanical properties were evaluated and compared with base alloy. Significant improvement in hardness and tensile strength were observed with the increase in the wt % Fe2O3. The microstructural studies of the composite showed a better dispersion of the Fe2O3 in the matrix.

Title: Optimization of Transmission Line Towers: P-Delta Analysis Authors: Vinay, R. B.; Ranjith, A.; Bharath, A. Abstract: Transmission towers are generally analyzed by linear static analysis methods and second order analysis are usually neglected. Linear static analysis does not reflect the structural characteristic of transmission towers. Structures that tend toward more taller and lighter, it will result in potentially more significant to the P-delta effects. The Present work describes the structural optimization of transmission line tower. In the study 400kV double circuit tower is modeled using Angle and Tubular sections using STAAD.Pro V8i software and analyzed for Wind load by using linear static and P-delta analysis in order to study the importance of P-delta analysis for transmission tower . After analysis, the comparative study is presented with respective to cost and displacement for both sections. A saving in steel weight up to 20.9% resulted when tubular section is compared with angular section. The displacement value increased when tower is analyzed for P-delta as compared to static analysis
