Archery is being contemplated from hundreds of years; however there have been not many investigations expressing and clarifying the optimal design and aerodynamic effectiveness of an Arrow. Presently Archery has turned into a significant game in Olympics. Every nation is showing colossal interest in delivering champions. So, it is important to work on the solidness of the Arrow to such an extent that its precision and aerodynamic characteristics improve. Broad examination is proceeding to work on the streamlined exhibition of the Arrow. So, this study intends to explore the aerodynamic characteristics of an Arrow for various fletches and diverse Arrow points. To accomplish this, the initial trends of aerodynamics characterization were obtained by XFLR5 v6.51 and then deep flow analysis was performed by Computational Fluid Dynamics using ANSYS Fluent. The outcomes are upon to show that the Arrow performs better at a speed range of 40-60 m/s and angles of attack from - 5 to +5 degrees. MATLAB is employed in plotting all of the non-dimensional data fluctuations, since it is the most trusted plotting software. The outcomes are validated with existing research work and significant conclusions are obtained.

Fluid Behaviour

The rheological behaviour of concentrated coal-water slurries prepared from three different Indian coals were investigated using an Anton Paar rheometer. The perspective was laid in to study the effect of solids concentration on the rheological behaviour of coal water slurry. It was observed that coal water slurry exhibited non-Newtonian pseudoplastic fluid behaviour at concentrations above 30 % by weight. The apparent viscosity varied with the amount of coal in the slurry. The rheological data were utilized to predict the pressure drop characteristics of coal water slurry flowing through a 53 mm diameter slurry pipeline using ANSYS Fluent 14.0 computational fluid dynamics code.

Thermal accumulation in a car cabin under direct exposure to sunlight can be extremely critical due to the risk of heatstroke especially to children who are left unattended in the car. There are very limited studies in the literature to understand the thermal behaviour of a car that is parked in an open car park space and the findings are mostly inconsistent among researchers. In this paper, the studies of thermal accumulation in an enclosed vehicle by experimental and computational fluid dynamics simulation approaches were carried out. An effective and economical method to reduce the heat accumulation was proposed. Different test conditions such as fully enclosed, fully enclosed with sunshade on front windshield and different combinations of window gap sizes were experimented and presented. Eight points of measurement were recorded at different locations in the car cabin and the results were used as the boundary conditions for the three-dimensional computational fluid dynamics simulation. The computational fluid dynamics software used was ANSYS FLUENT 16.0. The results showed that the application of sunshade helped to reduce thermal accumulation at car cabin by 11.5%. The optimum combination of windows gap size was found to be with 4-cm gap on all four windows which contributed to a 21.1% reduction in car cabin temperature. The results obtained from the simulations were comparable and in agreement with the experimental tests.
