THE INFLUENCE OF ISENTROPIC COEFFICENT AND REYNOLDS NUMBER ON THE MEASUREMENT OF 4-HOLE WEDGE PROBE

A 4-hole wedge probe was tested in a special designed wind tunnel with air, superheat steam and wet steam in different conditions. Experimental data were quantitatively analyzed to get the influence of isentropic coefficents and Reynolds number on the fluiddynamic measurement, and a meanful conclusion was made.
