Abstract: Due to rapid consumption of world's fossil fuel resources and impracticality of large-scale application and production of renewable energy, the significance of energy efficiency improvement of current available energy modes has been widely realized by both industry and academia. In the CNC machining field, the key solution for this issue is by increasing the effectiveness of the existing lubrication systems as it could reduce the power required to overcome the friction component in machining process. For more improvement, introducing the nanolubrication could produce much less power consumption as the rolling action of billions units of nanoparticle in the tool chip interface could reduce the cutting forces significantly. In this research work, the possibility of using carbon onion nanolubrication with DLC cutting tool is investigated to reduce the machining power consumption. Carbon onion nanolubrication has been successfully developed with high tribology performance and mixed with or

Abstract: The work carried out in this paper is aimed towards CFD study and empirical determination of parameters that effect the lift and drag coefficients of fixed wing micro aerial vehicles. Empirical formulae are devised for calculating these aerodynamic coefficients in order to alleviate the computational cost incurred by conventional high fidelity software tools. Two of the most widely used planform shapes for fixed wing micro aerial vehicles i.e. rectangular and Zimmerman shapes are chosen for study with cambered low Reynolds number airfoil E61. The results obtained using the empirical formulae are compared with that of ANSYS FLUENT[1] software. Moreover, flat plate results from wind tunnel experimentations by Thomas Mueller et al.[2] have been compared with corresponding FLUENT[1] CFD results as well as with the empirical formulation.
