Resumo
Flow patterns are found in many processes involving multiphase flows in the industry. This experimental investigation focuses on the behavior of the vorticity fields found in the liquid-vapor interface during flow boiling of R-600a with heat flux varying from 5 to 20 kW/m 2 and fixed mass flux of 890 kg/(m 2 s) at a saturation temperature of 17 ∘ C. Tests were performed in a horizontal tube with 1.0 mm ID. Four different flow patterns were identified based on images, and the vorticity fields were investigated using an optical flow method.
