Optimization of Solar Flat Plate Collector Area for Thermo-Siphon Type Solar Liquid Heating System Using Computer Program
Gautam S Kamble, Aishwarya B Patil, Trupti M Paymal, Sneha H Ghadage and Girija R Banchhode

The paper develops a model for Solar Flat Plate (SFP) collector of thermo-siphon solar liquid heater which is useful to build a computer design tool. While developing this procedure, all parameters are considered, so that the effect of each element and parameter on the design can be scrutinized thoroughly. The design of thermo-siphon systems is complicated by the fact that the mass flow rate 'G' is a function of system itself and hence it is difficult to calculate or predict 'G' at design stage. In addition to this, 'Utop' is required to estimate 'G'. Intricacy increases in design because 'Utop' is function of mean plate temperature 'Tpm' which is unknown and F' is function of 'Utop'. In this attempt, this complexity in 'G' is eradicated by tedious iterative calculations with the aid of computer which provides more reliable results. The consequences of different parameters on collector area for required fluid temperature have been investigated through this novel model. The effects of absorber plate materials, number of covers, collector fluids, plate to fluid resistance Rpf and inlet fluid temperature on required collector area are discussed. The results provide a precise approach to solar engineers in optimization of collector area at design stage.

SEM and Fractography Analysis of SiCp/Al2O3 Ceramic Matrix Composites Prepared Through Directed Metal Oxidation Process of Al Alloy
Malkapuram Devaiah

Ceramic Matrix composites (CMCs) of Al2O3 as matrix reinforced with Silicon carbide particulate composites with varying SiC volume faction were fabricated using DIrected Metal OXidation (DIMOX) process. Continuous oxidation of Al-8.5Si-1.5Mg-9Zn alloy in the presence SiC performed with suitable dopants led to the formation of the Al2O3 matrix. SiC reinforced Al2O3 matrix, ceramic matrix composites microstructural details and fracture behavior after fracture test have been discussed using Scanning Electron Microscope (SEM). The surface fracture of the broken fracture sample was observed under SEM. The paper made SEM studies on the composites prepared using directed metal oxidation process. Extra phases other than matrix and reinforcement could be observed clearly with the help high resolution offered by an electron microscope unlike an optical microscope. An Al-Zn-Si-Mg oxidized at 950 oC to 980 oC in air produced composite with 1-2 um channels at an average growth rate of ~0.25 mm/h. However, the experimental observations revealed that the growth rate increased with increase in particle size. The fracture of SiC/Al2O3 composites was found to be brittle in nature.

Design and Static Analysis of Composite Leaf Spring for Heavy Vehicle Suspension System
K S Naresh

A leaf spring is a most common form of spring used for suspension in heavy vehicles. Leaf spring is made up of a number of strips curved slightly upwards and clamped together one above the other. These plates are attached to the body frame and axle of vehicle. The suspension system in a vehicle is important to improve the riding comfort and stability of the vehicle. Leaf springs are commonly used in vehicle suspension system and are subjected to millions of various stress cycles, leading to fatigue failure; and it is necessary to determine the allowable stress and maximum deflection to avoid failure. This paper presents design considerations of composite leaf spring by applying static load and deriving the stresses and deformation in the leaf spring. Analytical calculation has also been done by CAD modeling using ANSYS 14.5 workbench. The results obtained by analytical and numerical calculation are in close agreement.

Optimization of Product by Value Engineering Job Plan Technique
G K Vinay Kumar and Himaanshu Kumaraswamy

Value Engineering (VE) is a scientific tool for reducing the cost while meeting the customer requirement. The paper uses steps of Value Engineering Job Plan (VEJP) to reduce the cost and improve the value of a rooftop extractor. A case study has been discussed involving roof exhausters which are used for circulation of air in most of the industries. The material is chosen such that the cost is reduced without affecting the quality of the product. Through the application of VE, profits are maximized without hindering the reliability of the product. With the effective utilization of the technique, the final outcome is a successful showcase of VE. Changes in design are also proposed.
