Fluid Dynamics Topics
- Acoustic Streaming
- Unidirectional flow currents in a fluid that are due to the presence of sound waves.
- Aerodynamic Drag
- Resistance of a vehicle body to motion through the air. A smooth surface has less drag than a rough one.
- Back Pressure
- Pressure exerted backward; in a field of fluid flow, a pressure exerted contrary to the pressure producing the main flow.
- Bernoulli′s Principle
- The pressure in a fluid decreases as its velocity increases.
- Boost Pressure
- The increase above atmospheric pressure produced inside the intake manifold by a forced-induction system such as a turbocharger or supercharger.
- Brookfield Viscosity
- Apparent viscosity determined by Brookfield viscometer.
- Centre of Pressure
- The point at which the aerodynamic forces on a body appear to act, and at which there is no aerodynamic movement.
- Computational Fluid Dynamics
- A tool for predicting the aerodynamics and fluid dynamics of air around flight vehicles by solving a set of mathematical equations with a computer.
- Differential Pressure Indicator
- An indicator which signals the difference in pressure between two points, typically between the upstream and downstream sides of a filter, valve or expansion element.
- Drag
- Resistance of a vehicle body to motion through the air. A smooth surface has less drag than a rough one.
- Drag Coefficient
- A dimensionless value that allows the comparison of shape and orientation of different bodies.
- Dynamic Pressure
- The pressure of a fluid resulting from its motion when brought to rest on a surface.
- Dynamic viscosity
- That molecular property of a fluid which enables it to support tangential stresses for a finite time and thus to resist deformation.

- Hydrostatic Pressure
- The pressure at any point in a liquid at rest; equal to the depth of the liquid multiplied by its density.
- Impact Pressure
- Another name for Dynamic Pressure.
- Kinematic Viscosity
- The dynamic viscosity of a fluid divided by the fluid density.
- Pressure
- Defined as the force exerted per unit area.
- Pressure Coefficient
- A dimensionless value which acts as a means of indicating the local pressure at some point of interest around a body, and which is independent of velocity.
- Pressure Head
- Pressure head is one of the main characteristics of a pump.
- Pressure Relief Valve
- A type of valve used to control or limit the pressure in a system or vessel.
- Pressure Zone
- As sound waves strike a solid surface, the particle velocity is zero at the surface and the pressure is high, thus creating a high-pressure layer near the surface.
- Profile Drag
- This is drag from the three-dimensional shape of the aircraft or vehicle.
- Saybolt Universal Seconds
- Another name for Saybolt Universal Viscosity.
- Saybolt Universal Viscosity
- The time in seconds required for 60 cubic centimeters of a fluid to flow through the orifice of the Standard Saybolt Universal Viscometer at a given temperature under specified conditions.
- Service Drag
- This is drag from air ducted to cooling components.
- Stagnation Pressure
- Another name for Dynamic Pressure.
- Total Pressure
- Another name for Dynamic Pressure.
- Vehicle Aerodynamic Drag
- Resistance of a vehicle body to motion through the air.
- Velocity Pressure
- The difference between dynamic pressure and static pressure.
- Viscosity
- A measure of the internal friction within a fluid.
- Viscosity Grade
- Any of a number of systems which characterize lubricants according to viscosity for particular applications.
- Viscosity Index
- An arbitrary measure for the change of kinematic viscosity with temperature.
- Viscosity Index Improvers
- Additives that increase the viscosity of the fluid throughout its useful temperature range.
- Viscosity Modifier
- Lubricant additive, usually a high molecular weight polymer, that reduces the tendency of an oil′s viscosity to change with temperature.
