Abstract
A velocity probe capable of measuring all the three components of a velocity vector simultaneously by correlating data from three or more thermocouples is shown and described.
Claims5
A measurement system comprising:
- a plurality of thermocouples;
- said plurality of thermocouples being located in a support component;
- said plurality of thermocouples comprising:
- at least three groups of thermocouples;
- thermocouples from each group of said at least three groups being located such that at a distance between at least one member of one group and at least one member of another group is selected to enable measurement of temperature/flow field features of a first predetermined characteristic length;
- and
- at least one thermocouples surrounded by said at least three groups of thermocouples;
- a third distance between said at least one thermocouples and at least one thermocouple from each of said at least three groups being selected to enable measurement of temperature/flow field features of a second predetermined characteristic length.
5 more elements
A method for determining velocity of flow, the method comprising:
- obtaining at least one cross-correlation between measurements of temperature in a flow field;
- and
- determining from said at least one cross-correlation a characteristic flow velocity.
