CFD Based Investigation on Delay of Boundary Layer Separation by Active Flow Control for NACA0084M Aerofoil

The unsteadiness such as boundary layer transition and turbulence at high angles of attack result in lift loss and increase in drag over an aerofoil. Numerous techniques such as suction at slots, flaps, bumps, high lift devices etc. have been developed by the scientists to control the separation delay and thereby prevent the aerodynamic losses at higher angles of attack. This research work aims at studying the effects of delaying the boundary layer separation by adopting blowing active flow control with local jets with varying velocity ratios and at different angles of attack on a 2D NACA 0084M aerofoil. Four different ratios of jet velocity (viz., 1, 2, 6 and 12) have been considered and the aerodynamic performance of each has been evaluated. The research aims to focus on the improvements in lift and drag characteristics of the above mentioned aerofoil and identify the best possible jet velocity.

Effect of Heat Stress on Amylase Activity in Chalky and Translucent Rice Genotypes

Occurrence of chalkiness is a major problem as it is an important parameter in determining quality of rice grains. High temperature during the grain filling period results in loose packing starch granules that could be due to involvement of starch degrading enzymes i.e., amylases. Therefore, two rice genotypes viz., PAU 3699-13- 2-1- 1 and PR122 were sown at two different dates. Thirty- day old seedlings of the two genotypes were transplanted in the field at two different times in order to expose the plants to different temperature regimes during grain filling. A Significant increase in total amylase activity was observed during early transplanting. The chalky genotypes i.e., PAU-3699- 13-2- 1-1 possessed higher α-amylase activity than translucent genotype (PR122) during heat stress. Whereas, PR122 possessed higher β amylase activity than PAU-3699- 13-2- 1-1. High temperature encountered during early transplanting resulted in induction of activities of amylases.

Isolation, Identification, Purification and Characterization of Antibiotic Producing Bacteria from Different Soil Samples

Streptococcus and Micrococcus luteus are the best source of antibiotic. In the present study 4 culture (Bacillus cereus(S6), Pseudomonas fluoresens(S1), Streptococcus(S2), Micrococcus luteus(S3) were isolated from 6 soil sample collected from Lucknow, Kanpur and Unnao. Isolation of microbes was done by serial dilution method. Primary screening of the culture was done by streaking. Gram’s staining was done to check the culture was pure or not. Identification was done by Bergey’s manual, further media optimization was done. Production media was prepared for these 4 culture in which the best carbon sources was Sucrose, Glucose, Dextrose, Sucrose best nitrogen sources were Yeast extract, the best temperature was 370C and best pH was 11,7,7,7(Micrococcus luteus, Streptococcus, Pseudomonas fluorescens, Bacillus cereus) respectively. Further extraction of seconda ry metabolite was done by using one solvent :(Chloroform) for extracellular component and (Methanol) for the intracellular component. Further purification of the antimicrobial compound using TLC (thin layer chromatography) and a spectrophotometer was performed resulting Quercetin compound.

Mid-Point Algorithm Based Sink Movement to Improve Lifetime of the Wireless Sensor Networks

The wireless sensor networks with the mobile sink are more effective in providing better network performance as compared to the ones with the static sinks. This paper proposes a scheme cluster based WSN with the tour planning of the mobile sink. Since the deployment of the nodes in the WSN is purely random, this leads to some nodes in the network not connected to any cluster (when the clustering is done). The proposed scheme takes into consideration cluster heads and unconnected nodes to plan the trajectory of the sink movement. The scheme was implemented in NS2.35 and compared with the existing approach based on the remaining energy, routing overhead and packet delivery ratio. The scheme has outperformed the existing scheme.

Various Mobile Sink Approaches for data aggregation in WSN: A Survey

A WSN is made of one or numerous distant sinks and numerous minute, low-power sensors, apiece equipped with actuators, sensing devices, and wireless transmitters and receivers. Sensors are generally power-driven by smaller batteries. The sink is normally static and located outside the network. This results in the increase of the communication distance between the far away cluster heads from the sink. These spent higher energies than those located close to sink. In order to balance the energy, this paper displays various clustering approaches that makes the use of the mobile sink to collect data from the cluster heads.

CFD Based Quantification of Aerodynamic Performance of an Automotive With Roof Dimples

The impact of aerodynamics on vehicle performance has gained greater importance in the modern days. The effecst of drag and lift forces on automotives have been well accounted for and engineers are relentlessly working on minimising the negative implications of these aerodynamic forces. The dimples on golf balls have been proven to reduce drag and are given credit for a golf ball’s longer flight. The use of dimples to reduce drag has often inspired many aerodynamists and this research aims to quantify the drag and lift forces on an automotive with dimples on its roof. A wide range of dimple ratios, arrangements and velocities have been taken into consideration and successful reduction in drag and lift coefficients has been reported.
