INTERFACE FLOW CHARACTERISTIC METRE AND MODE OF OPERATION THEREOF

摘要

FIELD: medicine. ^ SUBSTANCE: invention refers to experimental aerodynamics, particularly to a class of facilities to analyse various characteristics of a three-dimensional interface. An interface flow characteristic metre comprises a surface probe coil of a hot-wire anemometre comprising heating and heat-indicating elements integrated in a metreing system, and sensing circuit for constant E and pulsation e' flow characteristics on the surface of an aerodynamic body. Besides the working surface of said probe coil is circular with the heating element located in the centre of a circle, while the heat-indicating elements are attached to an ohmmetre and located on its radiuses. The method is implemented by said device. ^ EFFECT: orientation and characteristic metreing of a three-dimensional flow and with using the hot-wire anemometre with the surface probe coil. ^ 2 cl, 4 dwg
