product of the pressure, p, and specific volume, υ) exhibit abrupt changes across the
contact surface since the air is assumed to behave as an ideal fluid with zero thermal
conductivity so that there is no heat transfer between the driver and driven sections to
equalize the temperatures.
Fig. B.6 Plots of pressure, particle velocity and density as a function of particle position at
t ¼ 50000Δt and at t ¼ 160000Δt. For the numerical calculations the following parameters apply;
γ ¼ 1.4, κ ¼ 1.2, Δx ¼ 0.1 and Δt ¼ 0.005 (see text)
