For ideal gases, the detonation parameters calculated by this model are near to those calculated by CJ-ZND model.
对于理想气体,由该模型得出的爆轰参数与CJ -ZND模型相近。
These are tentatively explained from ZND model. The numerical results show that the adjacent medium affects the velocity and the shape of the detonation front nearby the node.
计算结果显示,毗邻介质影响节点附近的爆轰波阵面形状及爆轰波速度;
The order assumption in CJ and ZND models, which considers all particles of detonation products march orderly in one direction, implies low entropy and thermodynamic non-equilibrium.
CJ和ZND模型中的有序假设,即爆轰产物粒子朝着同一方向作有序运动的假设,决定了终点熵最低和不处于热力学平衡态。
However, it was still lack of systematic study of rheology of gel ZND. And the rationality, correctness and feasibility of the separating-type gel slug principle need to be verified yet.
②凝胶ZND是否能够形成隔断地层流体与井筒流体联系的隔断式凝胶段塞,所形成的凝胶段塞是否具有启动压力梯度及其调控措施仍需实验和现场试验证实;
