title = "Design of multiple channel hot wire anemometers",
abstract = "An anemometer design is presented which provides 138 channels of hot wire anemometry for simultaneous sampling of low frequency turbulent events. Each anemometer is fitted with a sample and hold circuit and an 8th order, low pass Bessel filter. There are 16 anemometers placed on a circuit board. A multiplexer is mounted on each board to select one of the anemometers for data output to an analog to digital (A/D) computer. Each board is therefore connected to only one channel of the A/D. With 16 channels of A/D and 16 anemometers on a board it is possible to measure at 256 different locations simultaneously. The cost of the individual anemometers was kept low (about \$50 each) so that many anemometers could be utilized. The experiment to which this anemometer design will be applied is the simultaneous sampling of the velocity field in the mixing layer of an isothermal, axisymmetric jet. Proper care is taken to resolve the entire flow field, thereby limiting the amount of spatial aliasing of the azimuthal modes. The use of long hot wires aids in the reduction of spatial aliasing.",
