The streamlines and mainstream velocity \(v_{x} \left( z \right)\) (the unit of velocity is \(\left( {{\varepsilon \mathord{\left/ {\vphantom {\varepsilon m}} \right. \kern-\nulldelimiterspace} m}} \right)^{1/2}\)) contour of methane fluid for selected state point using the mixture boundary Poiseuille flow model.
