Marginal VDF (47) at the receiver. a, b ϖτc=1.09 and (c,d) ϖτc=2.72. In both cases, \(\sqrt {\pi }\varpi {L}/v_{m}=20\). Solid lines represent the accurate results from the Shakhov model (44) solved by the discrete velocity method [69], while symbols are approximate solutions of the Shakhov model when the molecular velocity space v is discretized according to the Gauss-Hermite quadrature of order N
