AB - The advantage of “three against one” algorithm for determination of 3-D velocity field from the four hot-wires output signals is presented. Three tests of this algorithm, with differently defined dependence between velocity components and probe output signals are conducted. Test with generalized hot-wire cooling law shows better results in comparison to the test based on King-Jorgensen equations. It is shown that “three against one” algorithm has some advantage near the border of uniqueness range in comparison to the existing algorithms.
