Method for determining a two-dimensional or three-dimensional velocity vector of the liquid and gas flow and the vector electronic anemometer

摘要

a two-dimensional or three-dimensional manner determining vector speed flow of liquids and gases is that on the basis of the analysis of signals with i + 1, and 2 detectors size fluctuations physical promoting speed at least equal speed centredesignate times of ti flat surface izofazowej fluctuations in direction vector speed between p0 detectors p1 arranged points of known spatial coordinates, and on this basis, with the solution of equations of motion the flat surface izofazowej fluk tuacji as: si = ri (something? and -?) something? something? + sin? , sin? = vti,a flow velocity vector according to the formula (a). the subject of the invention is also an electronic anemometer vector.
