  • Mathematical algorithm for calculating the velocity vectors of fluid by CTA in spherical coordinates
    Šajn, Viktor ; Kotur, Milovan ; Kosel, Franc
    This paper presents a mathematical algorithm that determines the fluid flow velocity vector (direction, intensity and orientation), based on measured voltages on multi-channel hot-wire anemometer. As ... the voltage on Constant Temperature hot-wire Anemometer (CTA) is non-linear function of velocity and angle of the fluid, inverse function is also non-linear and has several mathematically correct solutions. In the Laboratory of Non-linear Mechanics at the Faculty of Mechanical Engineering in Ljubljana, the authors have decided to try developing multi-channel hot-wire anemometer with constant temperature at which it is possible to select physically correct solutions from several mathematically correct solutions. The mathematical algorithm works correctly if the range of instrument operation is limited for the value of spherical angles ...
