INVESTIGATION ON THE MECHANICALBEHAVIOUR OF THE GLASS/ BANANAFIBERS REINFORCED EPOXY COMPOSITE

The composites are one of the advanced engineering materials which are commonly used in this decade in day today life. The natural fibers are used for the reinforcement in order to get higher strength, reduced density, lower weight for several applications. The hybrid composite is obtained by using two or more materials with varying properties. Hybridization is a process of incorporating synthetic fiber with the natural fiber to get the better strength, stiffness, high strength to weight ratio and improvements in the mechanical properties. In this work, an attempt is made to hybridize using Glass (synthetic) fiber as well as Banana (natural) fiber with Epoxy resin as the matrix material, such that to reduce the overall use of the synthetic reinforcement and to enhance the mechanical properties.

Numerical Analysis of Flow through Channels Pertaining to Heat Sink with Flaps

Heat sinks with rectangular channels are generally used to dissipate heat from electronic components. To confirm munch angling heat dissipation of heat, coolant fluid has to be uniformly distributed among the channels of heat sink. In this research work, fluid flow is simulated computationally by using commercially available CFD software through the heat sink with flaps placed at the inlet of the channels. Major objective of this work is to study the effect of geometry of the flap on the uniformity of flow distribution among the channels. Length and inclination of the flap pivoted to the wall of the channel at its inlet are varied along with inlet flow velocity and flow rates in each of the channels are observed. It is observed that longer flaps with smaller angles and shorter flaps with larger angles result in better distribution of flow

This creates a big challenge for the upcoming generation. If improvement is not successful, there exists the unfortunate consequence that global food production may soon become insufficient to feed all of the world’s people. It is therefore essential that agricultural productivity be significantly increased in a more sustainable and environmentally friendly approach. Plant-beneficiary rhizo-bacteria (PBR) naturally activate microorganisms found in the soil. Because they are inexpensive, effective, and environmentally friendly, PBR are gaining impor-tance for use in crop production by restoring the soil’s natural fertility and protect-ing it against drought and soil diseases, thereby stimulating plant growth. PBR decrease the use of chemical fertilisers, pesticides, and artificial growth regulators; the intensive use of these inputs has led to severe health and environmental hazards, such as soil erosion, water contamination, pesticide poisoning, decreased ground-water table, water logging, surface crusting and depletion of biodiversity. The use of PBR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism with the aim of sustaining soil health over the long term.
