Abstract:
A fluid velocity measurement device comprising an approximately linear oblong body, a set of nonlinear prongs and a cross-wire combination, said body being approximately characterized by a geometric longitudinal body axis, said body having a first body axial extremity and a second body axial extremity, said first body axial extremity and said second body axial extremity being at opposite longitudinally axial extremes of said body, said prongs protruding from said body at said first body axial extremity, said nonlinear prongs having corresponding prong tips distanced from said first body axial extremity, said cross-wire combination communicating with said prong tips, said nonlinear prongs and said body together approximately defining a geometric device plane passing therethrough, said cross-wire combination approximately defining a geometric cross-wire plane passing therethrough, said cross-wire plane and said body axis being approximately parallel to each other, said cross-wire plane and said device plane being approximately perpendicular to each other, said device being adaptable to electrical connection with a hot-wire anemometer at said second body axial extremity, said set of nonlinear prongs including four nonlinear prongs which are approximately congruously nonlinear, said cross-wire combination including two electrically conductive wires which are disposed next to each other in approximately perpendicular crisscross fashion, said four nonlinear prongs securing said two electrically conductive wires at the ends of said electrically conductive wires, said two electrically conductive wires corresponding respectively to the x and y components of a fluid velocity vector, said hot-wire anemometer being capable of determining fluid velocity based on the temperature and electrical current associated with said two electrically conductive wires.
