Super-cavitation is the state of the art technology that may revolutionize underwater propulsion systems. Super-caviatating bodies can achieve very high speeds under water by virtue of reduced hydrodynamic drag with respect to fully wetted underwater vehicles. A cavitation bubble is generated at the nose, by virtue of that skin friction drag is drastically reduced.This study will be carried out to investigate various aspects of axisymmetric super-caviatating projectiles. In this project, it is aimed at the optimization of the cavitator shape for axisymmetric bodies in partially caviatating...

The enormous growth in the field of biotechnology has brought a great demand to amino acid production due to its wide variety of applications in food, medicine, cosmetics, and as a starting material in the chemical industry. Glutamic acid, a non-essential amino acid and is synthesized from a number of amino acids including Ornithine and arginine. Free glutamic acid is present in a wide variety of foods, including cheese and soy sauce and is responsible for one of the five basic tastes of the human; sense of taste .It is often used as a food additive and flavor enhancer in the form of its...

In the present study, the numerical study is carried out for boundary layer flow over 3D aerofoil section and the aerodynamic performance of NACA aerofoil are analyzed by studying the lift and drag coefficient of the aerofoil.The results obtained in the case of boundary layer flow over the 3D aerofoil section are compared with the experimental data as available in the literature. The experimental data for NACA 64-009 from wind tunnel is validated with simulations results computed in FLUENT. The aerofoil is cambered and measured to be around 1mt. The simulations for boundary layer flow for...

For moving ahead ship needs thrust, which is generated by rotating propeller behind its hull. Propellers are used to generate thrust to propel marine vehicles. Propeller generates thrust by virtue of the pressure difference between two surfaces of the propeller blade, called face and back. The incident angle of the flow plays a major role in generating this pressure difference over every blade section (which is an aerofoil section in general). A controllable pitch propeller can adjust incidence of incoming flow and can offer better control over the thrust generated by it.Traditionally thrust...
