achieve similitude; 1. Geometric similarity – The model is the same shape as the application (they are usually scaled). 2. Kinematic similarity – Fluid flow of both the model and real application must undergo similar time rates of change motions. (Fluid streamlines are similar). 3. Dynamic similarity – Ratios of all forces acting on corresponding fluid particles and boundary surfaces in the two systems are constant. BEFORE THAT!! The application is analyzed in order to satisfy the conditions; 1

was compared with the predicted one. From this experiment it was obtained thatthe pressure drop increase as increasing the fluid (water or air) rates until it reach constant value. In addition‚ the bed height is constant as flow rate increased in fixed bed and it is increased as the flow rate increased when fluidization occurred. Furthermore‚ it was found that the air fluid requires higher flow rate than water in order to fluidize the bed. 1 Nomenclature Symbols Dp ε ρa μ ρs ρw A Φs L D V

first is a colloid of silicon dioxide particles suspended in polyethylene oxide. this liquid is a Shear thickening fluid which hardens on impact. the second liquid used is a magnetorheological (MR) fluid. MR fluids are oils that are filled with iron particles and can change its viscosity to a solid state when a magnetic field is applied to it. The third section of the poster

BLISK 1. BLISK or IBR (Integrated Blade Rotors) are among the most innovative and challenging components in modern gas turbine engines. BLISK may be integrally cast‚ machined from a solid piece of material or made by welding individual blades to the rotor disc. Initially BLISK was used only in first stage LP compressor. Its low weight and excellent aerodynamic efficiency making it popular for use in the HP stage also. CONVENTIONAL DISK Vs BLISK 2. Conventional rotor disk comprises rotor blades

program From the main menu‚ choose Cardiovascular Dynamics The program should open in the “Vessel Resistance” window‚ but if it doesn’t then you should click Experiment and choose Vessel Resistance. The experimental apparatus is a set of 2 fluid reservoirs connected by a “blood vessel”. It is possible to vary the values of blood pressure‚ blood viscosity‚ vessel length and vessel radius by clicking on the + and – buttons next to those parameters. Once your values have been chosen‚ you can

Homework Introduction to Aerodynamics Name: Natalie Hume 1. In your opinion what has been the most important development/invention in the history of aerodynamics and why? I feel that I could pick something very complex and technical for this question. But I think in terms of science and simplicity I pick Bernoulli’s principle. This principle laid the foundation for the development of aerodynamics. It allowed for people to understand the relationship between pressure and velocity and continue

wave equation is an important second-order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves‚ light waves and water waves. It arises in fields like acoustics‚ electromagnetic‚ and fluid dynamics. Historically‚ the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’Alembert‚ Leonhard Euler‚ Daniel Bernoulli‚ and Joseph-Louis Lagrange.
