Winglet are small extension of wing. Which is attached to wing structure at the root tip with appropriate cant angle. The main aim of this project is to implement a suitable winglet to a UCAV wing and improve the performance and efficiency of UCAV wing by reducing a drag due to lift and increase lift to drag ratio. The wing of 10m span length and a NACA 6 digit series of airfoil section are considered. This airfoil has lower drag at higher speed when compared to 4 or 5 digits series. Among these airfoils NACA 64A210 has been chosen for the UCAV wing. For this UCAV wing the winglet has been designed using CATIA V5R20. Here designing has been done for winglet parameters in five cases by varying the cant angles i.e. 5°, 22.5°, 45°, 67.5°, and 90° for this different cant angle the CFD flow analysis were carried out by using ANSYS V14.5. Now a results of UCAV wing with and without winglet are compared with graph of aerodynamic parameters such as C l , C d and C l /C d with varying AOA at different velocities.

Optimization of pump characteristics when supporting the mechanical functions of heart as destination therapy is essential because of limitations imposed on design on size and power. Computational uid dynamics assessment with uid bearing similar properties is done. Knowledge of previously designed similar pumps is an 5 added advantage. Pumps supporting heart operate in Reynolds numbers of 10 .Limited data is available on pumps that operate in this range. It is useful to present data using traditional Cordier diagram of nondimensional speed vs diameter. Flow, pressure and rotational speed are the main parametric analytic points. Similitude helps in efcient design concept.

The paper analyzes the flow through axial turbine stages and the results of two numerical simulation of steady and unsteady flow are presented. Generally analysis of turbines is carried on individual blade rows i.e nozzle guide vanes (NGV) and rotor blades. It doesn't take the nonuniformity of the exit conditions of the upstream blade vanes. Hence, turbine stage analysis must be carried out to predict the stage performance. In this study an integrated approach to analyze the turbine stages by computational fluid dynamics (CFD) tools using Fine /TURBO is carried out.
