摘要
暴露在x射线辐射场中的圆柱壳体,在吸收了大量的辐射能后其表层汽化。由于表层的汽化物质快速飞散,圆柱壳体将受到冲击载荷的作用。本文用气体动力学方法提出了计算作用在圆柱壳体上汽化反冲压力及冲量的理论模型。
When the cylidrical shell is exposed to the x-ray energy flux, the radiant energy can sublimate the surface layer, provided the levels of absorbed radiant energy are sufficiently high. This extremely rapid sublimation can produce impulsive loads on the cylindrical shell due to the momentum transfer resulting from the rapid movement of the surface particles. With a gas dynamical method, the blowoff impulse is derived in this parper.
