Abstract: On the viewpoint that the
solid-gas two-phase flow consists of subsystems: solid granules
and gas, this paper analyses in greater detail the energy
distributive relation of the solid and the gas subsystems and
energy exchange between them under the circumstances of dilute
phase. Suspension energy of the granule has been obtained by
means of the fluid equation of energy. The new viewpoint has
been advanced that suspension energy is the viscous dissipation
function of fluid. And we have deduced the formula calculating
pressure loss and the equation of motion of granule group in
straight pipe from energy balance of the two subsystems, which
explains some motion group in straight pipe from energy balance
of the two subsystems, which explains some motion
characteristics of the granules in the two-phase flow.
