This rib is also suitable for a variety of loading conditions. Forged ribs are manufactured using heavy press-machinery, and are used for sections where very high loads apply. Milled ribs are solid structures, manufactured by milling away excess material from a solid block of metal, and are also used where very high loads apply. The stringers on the skin panels run in the length of the wing, and so usually need to bridge the ribs. There are several methods for dealing with this problem. The…

1024 Chickens Europe has turned to Skynet for farming advice. European Union agriculture commissioner Phil Hogan announced last Friday a multi-billion dollar plan to integrate digital sensors in every aspect of crop production to “produce more with less.” For instance, data from satellites could determine how best to apply fertilizers and pesticides, thus improving efficiency and crop yields. This undertaking would have been unthinkable a decade ago. But a new advance - parallel…

Particle Deformation and Fragmentation: As compaction force increases, contact area between particles increases, particle deformation starts to occur. Elastic deformation: granules attempt to return to their original shape or form after stress is released. Plastic deformation: granules do not totally recover after stress is released. Fragmentation occurs when compaction force continues to increase Particles fracture, create multiple new surface sites, additional contact points and potential…

Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…

Mathematical model Heat and mass transfer properties of counter flow wet cooling tower are obtained through the balance of mass and energy equations. The assumptions made for deriving the governing equations are listed below [14, 15]: • Heat and mass transfer take place only normal to the flow direction. • Heat transfer to the environment through the walls are negligible. • Heat transfer from cooling-tower fan is negligible. • Specific heats of water and dry air are constant. • Heat and mass…

SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

Tribological behavior of double-glow plasma Zirconium-Yttrium alloying on γ-TiAl Cong Huang, Pingze Zhang*, Dongbo Wei, Xiangfei Wei, Xiaohu Chen and Feng Ding (College of Materials Science and Technology, Nanjing University of Aeronautics and Astronautics, Nanjing 211100, China) * Corresponding author: pzzhang_nuaa@126.com Abstract: A Zr-Y alloyed layer was prepared onto the surface of γ-TiAl using double-glow plasma surface alloying technique (DG technique). The results showed that the Zr-Y…

Lab 1: Flow Visualization Jintark Kim Purdue University ME309 lab Section 009 Abstract The purpose of this experiment is to visualize and analyze the flow patterns formed by objects in different conditions: cylinders in different diameter at different flow rate, and airfoils with different angle of attack at a constant flow rate. Properties of water at measured temperature and flow conditions for each trial were used to compute the Reynolds number. Red-dye ejector was used to traces the…

The purpose of this lab is to evaluate the relationship between kinetic friction coefficient and static coefficient as well as measure the coefficients of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the…

Introduction Theoretically, energy in every isolated system will always be conserved so for every action there will be a reaction to stabilise the system (Ellert, G, n.d.). Such a term does also appear in the physics of fluids motion. Fluids are things that can flow such as gas, water or oil. In fluid motion physics there are two theories that are involved with the law of conservation and they are Bernoulli’s law and continuity equation. Bernoulli’s law is derived from the energy conservation…
