Peristaltic pumping in a two-dimensional conduit using vibrations the form of traveling waves has been investigated. Two qualitatively different responses producing vastly flow rates have identified, with transition occurring at wavelengths order opening. The rate is always proportional to wave phase speed and second power amplitude. Long produce sloshing which extends across whole small, nearly wave-number-independent rate. use such in-phase on both walls eliminates this while out-of-phase...

Flow control is a significant topic of research in the field aviation. Researchers this are continuously trying their best to find various flow strategies order extract aerodynamic benefits by applying them. Applying moving surface at leading edge aerofoil type strategy among types active strategies. In present work rotating cylinder added on as over its surface. The boundary layer applied NACA 0018 airfoil for investigating and effectiveness. created smooth aerofoil. peripheral velocity...

Aerodynamics of the rotary leading edge aircraft wing was experimented by help modified NACA-0010 airfoil. CFD simulation done converting 2-D airfoil to a 3-D wing. A cylinder mounted at and then it allowed rotate in anti-clockwise direction certain rpm. The showed that there significant improvement lift generation Parametric approach zero degree angle attack when symmetric typically doesn't generate any all but due effect positioned finite amount generation. for this model different keeping...

The growing interest in development of UAV has created a need for the comparative analysis performance parameters different aerofoils. Using this concept characteristics aerofoils are explored to design wing various fulfilling purposes. In research work, requirements our desired established. These translated into parameters. Then aerofoil that best meet was optimized from arbitrary through experimental investigation

Improving the aerodynamic performance of wing has always been an interesting topic research to aerodynamicists. Keeping this into consideration, various researchers have attempted improve in ways. Some them are suction, blowing, vortex generators, turbulence promoters etc. A vast literature accumulated over years. Compared them, use moving surface on improvement airfoil drawn little attention. This concept employs rotating cylinder at locations airfoil. aims investigate variation as a result...

In order to maintain the operational continuity of air defense systems, unmanned autonomous or remotely controlled aerial vehicle (UAV) plays a great role as target for anti-aircraft weapons. The must comply with requirements high speed, tracking and navigational aids, sustainability sufficient loiter time. It can also be used reconnaissance, ground surveillance other intelligence operations. This paper aims develop complete tail design an using Systems Engineering approach. fulfils...

Nowadays the role of computational fluid dynamics to predict flow behavior over airfoil is quite prominent. Most often a 2-D subsonic simulation carried out an at certain Reynolds number and various angles attack obtained by different turbulence models those are based on governing equations. The commonly used K-εpsilon, K-omega, Spalart Allmaras etc. Variation in model effectively influences result analysis. Here comparative study represented show effect for analysis National Advisory...

In classical theory of elasticity, external loading acting on the body is independent deformation body. But, in aeroelasticity, aerodynamic forces depend attitude relative to flow. Aircraft's are subjected a range static loads resulting from equilibrium or steady flight maneuvers such as coordinated level turn, pitch and bank rate, flight. Interaction these with elastic aircraft structure creates some aeroelastic phenomena. this paper, we have summarized recent developments area...
