Acoustic Doppler Velocimeter (ADV)
The Acoustic Doppler Velocimeter (ADV) is a tool that is designed to record instantaneous velocity components at a single-point with a relatively high frequency. The measurements are performed by measuring the velocity of particles in a remote sampling volume. It consists of a probe head made of 3 to 4 receivers. The measuring distance can be anywhere between 5 and 15 centimeters from the probe head. Figure 1 shows a diagram of a standard ADV.

ADV in Manifold Research
The ADV used in for the manifold research was a Nortek Vectrino. It was positioned outside of each port in order to measure the velocity in each jet. Through use and acclimation to this particular model, it was found that the probe head should be positioned approximately 17 cm (instead of the suggested 15 cm) from the sampling volume. Figure 2 shows the position and placement of an ADV in the inlet manifold model.

(Acronyms like ADV should be spelled out at least once in your document. How does ADV work? What software was required? Can you provide a brief procedure with screen shots for how someone would use the software in the future?)
