Aerodynamicheating is the heating of a solid body produced by the passage of fluid such as air over a body such as a meteor , missile , or airplane . It is a form of forced convection in that the flow field is created by forces beyond those associated with the thermal processes. The heat transfer essentially occurs at the vehicle surface where aerodynamic viscous forces ensures that the flow is at zero speed relative to the body for a very small layer of molecules at the surface. Because the flow has slowed to zero speed at this point a significant amount of its kinetic energy from the free field is converted to heat. In high speed flows, tremendous energy is represented by the mean motion of the flow. As the flow is slowed to zero speed, its temperature is increased. But the gradient in the speed in the direction normal to the surface allows small scale mass transport effects to dissipate the temperature in the outward direction and thus the temperature at the surface is less than the stagnation ... temperature and the mass flow rate of the flow.

Sample is heated by a CO sub 2 sub laser and temperature is measured from sample brightness by a pyrometer. Aerodynamic levitation is the use of gas pressure to levitate materials so that they are no longer in physical contact with any container. In scientific experiments this removes contamination and nucleation issues associated with physical contact with a container. Overview The term aerodynamic levitation could be applied to many objects that use gas pressure to counter the force of gravity , and allow stable levitation . Helicopters and air hockey pucks are two good examples of objects that are aerodynamically levitated. However, more recently this term has also been associated with a scientific technique which uses a cone shaped nozzle allowing stable levitation of 1 3mm diameter spherical samples without the need for active control mechanisms ref citation author Paul C.

In general, particles have irregular shapes with actual geometric diameters that are difficult to measure. Aerodynamic diameter is an expression of a particle s aerodynamic behavior as if it were a perfect sphere with unit density and diameter equal to the aerodynamic diameter. Such a model has the same terminal settling velocity . Aerodynamic diameter is commonly applied to particulate pollutants and inhaled drugs to predict where in the respiratory tract such particles will deposit.

Image aeroforces.svg thumb Forces on an aerofoil. Aerodynamic force is the resultant force exerted on a body by the air or some other gas in which the body is immersed, and is due to the relative motion between the body and the fluid. An aerodynamics aerodynamic force arises from two causes ref Hurt, H.H.Jr. Aerodynamics for Naval Aviators . p.29 ref ref Clancy, L.J. Aerodynamics . Section 4.10 ref ref Massey, B.S. Mechanics of Fluids , section 10.8.2 ref br the Surface force force due to the pressure on the surface of the body br the Surface force force due to viscosity , also known as skin friction When a body is exposed to the wind it experiences a force in the direction in which the wind is moving. This is an aerodynamic force. When a body is moving in air or some other gas the aerodynamic force is usually called drag force drag . When an airfoil or a wing or a Glider aircraft glider is moving relative to the air it generates an aerodynamic force that is partly parallel to the direction of relative motion, and partly perpendicular to the direction of relative motion. This aerodynamic force is commonly resolved into two components ref Hurt, H.H.Jr. Aerodynamics for Naval Aviators . p.14 ref ref Clancy, L.J. Aerodynamics . Section 5.3 ref Drag force Drag is the component parallel to the direction of relative motion. Lift force Lift is the component perpendicular to the direction of relative motion.

Unreferenced stub auto yes date December 2009 Joule heating , also known as ohmic heating and resistive heating , is the process by which the passage of an electric current through a conductor material conductor releases heat . It was first studied by James Prescott Joule in 1841. Joule immersed a length of wire in a fixed mass of water and measured the temperature rise due to a known current flowing through the wire for a 30 minute period. By varying the current and the length of the wire he deduced that the heat produced was proportionality mathematics proportional to the square algebra square of the current multiplied by the electrical resistance of the wire. math Q propto I 2 cdot R math This relationship is known as Joule s first law Joule s First Law . The SI unit of energy was subsequently named the joule and given the symbol J . The commonly known unit of power, the watt , is equivalent to one joule per second. It is now known that Joule heating is caused by interactions between the moving Subatomic particle particles that form the current usually, but not always, electrons and the atom ic ions that make up the body of the conductor. charge physics Charge d particles in an electric circuit are acceleration accelerated by an electric field but give up some of their kinetic energy each time they collide with an ion.

Most heating elements use Nichrome 80 20 80 nickel , 20 chromium wire, ribbon, or strip. Nichrome 80 20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the wire will not oxidize, preventing the wire from breaking or burning out. Resistance wire may be wire or ribbon, straight or coiled.
