forces (Anderson 2007). External flows past objects have been studied extensively because of their many practical applications. For example‚ airfoils are made into streamline shapes in order to increase the lifts‚ and at the same time‚ reducing the aerodynamic drags exerted on the wings. On the other hand‚ flow past a blunt body‚ such as a circular cylinder‚ usually experiences boundary layer separation and very strong flow oscillations in the wake region behind the body (Anderson 2007). In certain Reynolds

Dr. A.M. Surendra kumar Project Area: Aerodynamics‚ Fluid Dynamics‚ Elasticity Abstract: The traditional process of aerodynamic design is carried out manually by trial-and-error method. This process requires a large number of design engineers working alongside a huge budget. In order to overcome this manual method‚ the technologically driven software design using CFD will provide a cost effective optimal design method. Software products for automatic aerodynamic design are intended to solve the basic

Today I will be talking about paper airplanes and what type of paper airplane flies the farthest also which one stays aloft the longest. Some of the topics I plan to discuss involve aerodynamics‚ drag‚ shape‚ size‚ forces‚ and gravity. Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction‚ when air rubs against the surface‚ and difference in air pressure. Think of a drag like swimming treading through the water you can’t

design itself. Before the induction into the service the aircraft could have undergone many design improvements in order to meet the desired performance. These performance improvements can be achieved by improving the original design in the area of aerodynamics‚ structure (weight reduction)‚ propulsion and systems (like flight control system‚ avionics‚ fuel system etc.). This could be by modifying the original design or introducing new concepts in the design. Due to the obsolence of many technology and

models‚ which are not suitable for detailed design. is thesis describes the development of an aerostructural model for wind turbines with a high delity structural solver. is is done by coupling an existing high delity structural solver with an aerodynamic solver. Coupling is done by interfacing the components in Python. e aeroelastic solution is computed using the non-linear block Gauss-Seidel method. e code makes it possible to do
