Experimental and Numerical Study on Pressure Distribution of 90° Elbow for Flow Measurement

Figure 5

The typical pressure contours of 90° elbow at various pipe sections for helium gas flow under the condition 250°C and 7.0 MPa (mean velocity 𝑣 = 24.9 m/s, Re ≈ 1.3 × 10⁶). (a) Cross section position of a 90° elbow; (b) static pressure contours of eight cross sections; (c) static pressure distribution along the midline of 90° elbow in selected planes I, III, V, VI, and VIII.
