Top Tensioned Risers ( Ttrs ) For Dry Tree Production Facilities Like Spars And Tension Leg Platforms

Turbulent flow is the flow of fluids in a chaotic way due to property changes. The Reynolds number is higher than that of laminar flow making it able to freely move. They create a rotational high energy movement. Eddies are a good example of turbulent flow off of jet streams. They create that vortex circular motion and are high energy to start and will

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

Suspension bridges usually experience torsional forces during very windy conditions where there are high wind speeds, this can create a twisting force causing the deck to rotate resulting in the bridge experiencing shear stress. (Bagga

As the riders travel through some of the water areas, they will experience some inertia as the carts pass through. However, the momentum of the carts will be so fast, that the resistance of the water won’t

Recently, oil companies have increased their search for oil in water deeper than 1,500 feet, which is classified as "deep water." While that is where the companies hope to find the largest untapped oil reserves, seeking out and extracting oil there presents unique challenges. For one thing, platforms in deep water cannot sit on legs connected to the sea floor the way they can in shallower areas, so other methods must be used to protect them from strong currents.

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

The following report is based on an experiment conducted to calculate the lift curve slope for a symmetrical aerofoil subjected to varying angles of attack. Pressure readings were taken at different points on the upper and lower surface of the aerofoil. The report concludes that maximum lift is generated between 12 º -15º, which is also the stall point. It also states that region close to the leading edge contributes most to the lift force.

Professor Farquharson made an important observation- the bridge model underwent a “twisting motion” when faced with certain extreme conditions. From his model, he could conclude that in the event that the actual bridge

start from science call aerodynamic to decrease the vehicle “air resistance” to go faster until it brings into our daily life, nowadays a lot of our daily object we own include streamlining, it may not necessary streamlining but very curvy line organic line and so on. The reason why streamlining is around us because streamline gives us sleek, clean and modern look. For example, a sharp angle chair and curved chair, most of the time people would prefer curvy chair not only for how its look but also its comfortable and its ergonomics. Other than that, streamlining is not just a curve shape or an angle its actually speak thousands of words, same as on the graphic, its speak a lot for the graphic/

This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies between experimental and theoretical values.

Float equipment are a fundamental aspect of cementing operations, which serves as a foundation for casing equipment. They are commonly used in the lower section of the casing and help reduce the stress applied to the derrick by allowing the casing to be floated into place. According to Weatherford oil and gas service company, “they guide the casing to total depth, prevent contaminated mud from entering the casing, provide a landing point for casing wiper plugs, reinforce the lower end of the casing string, and ensure greater accuracy of cement slurry displacement”. Floating equipment is typically made up of 2 or 3 important tools, which include a float collar and float shoe or guide shoe. This paper will focus on the mechanisms and

The lid-driven cavity flow is most probably one of the most studied fluid problems in the
