Abstract:
Based on the simplified tw o-fluid model under the assumpt ion of dilute gas-part-i cle suspensions, the complex tw o-phase f low by projectile base f low ing from ax isymmetrical in base bleed projectile has been invest igated by using high accuracy and high resolut ion schemes. T he basic features of the now-equilibrium two-phase f low which are dif ferent from part icle density that affect s base drag reduction be changed. Compared experiment, That is bet ter than one-gas flow about g as-part icle.
