The aim of this work is to analyze how the flow into an aneurysm changes using different stent configurations. The initial conditions for the simulations were constructed from angiographic images of a real patient with an aneurysm.
When the driver pushes the brake, the calipers push both brake pads against the carbon brake disk to slow the car. Camber Camber is expressed in degrees, denoting the angle that a tyre stands on the ground compared to a vertical axis.
A camber of 0 means perfectly vertical wheels. Negative camber is frenquently seen in Formula One, noting that the upper part of the wheel is closer to the car's centerline than the bottom. On racing cars, this is frequently done to optimise grip in corners in an attempt to increase the contact surface of the outside wheels when the car is in roll.
Carbon brake disc Formula One racecars are equipped with brake discs manufactured of carbon fibres. This gives a fair decrease in weight over steel, but also impressively short brake distances. Considering that overheating may lead to malfunction, cooling and brake ducts are crucial Carbon Fibre Material that has small fibres or "hairs" of carbon added for strength.
The base material is typically plastic, which can be moulded and shaped as required. More on carbon fibre in F Carbon nanotube Single-wall carbon nanotubes SWCNTs can be considered to be formed by the rolling of a single layer of graphite called a graphene layer into a seamless cylinder.
Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites. Carburetor A device through which air and fuel are atomized and drawn into the engine.
It meters the proper proportions of fuel and air to form a combustible mixture and varies the ratio according to the engine operation. Caster Another measure of chassis tuning related to the front wheels.
The front wheels are attached to the suspension at the top and bottom of the wheel assembly. The top attachment is typically set a little farther back than the lower attachment, creating caster. The more caster used, the more the wheel resists turning forces, providing stability.
Too much caster makes it very difficult to steer, and causes the tire camber to change significantly as the wheel is turned. Not enough caster results in the front end "wandering," or trying to turn on its own.
Catalyst Substance that, by its presence, modifies the speed of a chemical reaction without changing in the process. Centre of pressure The point at which the aerodynamic forces on a body appear to act, and at which there is no aerodynamic movement.
It is similar the centre of gravity in mechanical terms. Chassis Backbone on which a car is based. Older racing cars had a steel or wood chassis.
Today's cars use carbon fibre. Chicane A tight combination of two corners in opposite direction. Most of the time slow and with curbes. Chimney Often used on F1 cars between anda chimney is a cooling and aerodynamic element positioned ahead of the rear wheels on the sidepod.
It is an open, aerodynamically shaped pipe that allows the hot air from within the sidepod to escape and flow over the rear wheels. Such devices are banned in F1 since Chord The distance between an aerofoil's leading edge and its trailing edge.
Clean air Usually experienced only by the car in front, the air behind the leader and the rest of the cars is turbulent and can affect the aerodynamics needed to achieve the smoothest drive. Clerk of the course Is the person ultimately responsible for all operational on-track issues related to the running of a motor race meeting.
Clutch Foot pedal that disengages the engine from the driveshaft. Used during gear changes. Today's F1 cars use semi-automatic gearboxes, so that these are not necesarry.
In Formula One it is a particularly useful effect in the design of the aerodynamics of a car. Cockpit Part of a race car where the driver sits and the hub of all the car's controls. In any car, this is the central part around which all safety measures are taken. Formula One cars as well as all modern single seaters or Le Mans prototypes host the cockpit inside the monocoque, making it an integral part of the chassis.Computational Fluid Dynamics (CFD) Computional Fluid Dynamics: Computers provide solutions to the problem of external airflow over vehicle shapes.
The body of the configuration and the space surrounding it are represented by clusters of points, lines and surfaces; equations are solved at these points. CFD is divided into three steps. The underlying assumptions and mathematical constraints involved with Computational Fluid Dynamics has made it an ART rather than a science or industrial engineering application.
It will involve asking questions like “What is the length of pipe upstream the if one says that he is simulating flow through a U-bend, it is always assumed. Free Excel/VBA Spreadsheets for Heat Transfer (Fluid Mechanics, PDE's, Thermodynamics and Numerical Methods, too) This workbook computes the Nusselt number for forced convection in a circular pipe as a function of the Reynolds (based on diameter) and Prandtl numbers (and where appropriate one or two other parameters).
