Abstract: The model problem of heat transfer from a nonuniformly heated pipe wall to the basic flow is considered, or, in other words, the initial stages of fluid temperature and pressure relaxation in a heated pipe are addressed. The computations are based on computer codes using various combinations of the Navier–Stokes equations, a modified Burnett equation, and the kinetic BGK equation.
Key words: Boltzmann equations, Navier–Stokes equations, Burnett equations, macroscopic flow variables, Chapman–Enskog method, BGK equation.
