AB - <p style="text-align: justify;">We investigate unidirectional rarefied flows confined between two infinite
parallel plates with specified heat flux boundary conditions. Both Couette and force-driven
Poiseuille flows are considered. The flow behaviors are analyzed numerically
by solving the Shakhov model of the Boltzmann equation. We find that a zero-heat-flux
wall can significantly influence the flow behavior, including the velocity slip and
temperature jump at the wall, especially for high-speed flows. The predicted bimodal-like
temperature profile for force-driven flows cannot even be qualitatively captured
by the Navier-Stokes-Fourier equations.</p>
