Determination of the magnitudes and signs of flow parameters by hot‐wire anemometry. Part I. Measurements using hot‐wire X probes

摘要: This article deals with the determination of magnitude and sign three components instantaneous velocity vector from output signals a triple‐sensor hot‐wire probe. All sensors lie in same plane given angular orientation. Measurements this triple probe are performed wire inclined at an angle about 45° to main transport direction fluid, thus ensuring high sensitivity flow sense. Furthermore, region applicability accuracy values parameters method discussed.
