Hydrodynamics of Cloud Collisions in Two Dimensions: The Fate of Clouds in a Multiphase MediumhydrodynamicsISM, cloudsISM, kinematics and dynamicsWe have studied head-on collisions between equal-mass, mildly supersonic (Mach number 1.5) HI clouds, in a standard Two-phase ISM (T_cl = 74 K, ...
Describe elastic collisions of two objects with equal mass. Determine the magnitude and direction of the final velocity given initial velocity, and scattering angle. In the previous two sections, we considered only one-dimensional collisions; during such collisions, the incoming and outgoing velocities...

In this study, as a continuation of the investigation why such remarkably different incident fluids produce such similar ejecta, we use discrete particle simulations to collide two unequal-width granular jets head-on in two dimensions. In addition to the familiar coherent ejecta, we observe that ...

aThe structure parameters which characterize dimensions of phase in the blends, as the correlation distance ac, and the average chord lengths of two-phase, as PPil and PcBR,lare calculated by data of scattering intensity. 在混合描绘维度阶段,比如交互作用距离ac和平均弦长的两相,作为PPil和PcBR, ...
The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking acco...
