Droplet dynamics in a polymer electrolyte fuel cell gas flow channel: Forces, Deformation and detachment. II: Comparisons of analytical solution with numerical and experimental results

► Dynamics of liquid water droplets in a PEM fuel cell channel is analyzed both experimentally and numerically. ► Droplet shape change and detachment are visualized by high resolution CCD camera. ► Droplet deformation and detachment is simulated by using Volume of Fluid method. ► Both experimental and numerical data show good agreements with analytic solution. ► The analytical solution of the We-Re correlation is validated in a certain range of H/r values.
