Hypergolic droplet‒film interaction dynamics at high temperatures

Droplet, EarlyView.
The whole reaction process can be distinctly identified as three stages based on the corona size and the temperature temporal evolution. In the coalescence regime, T* maintains quasi‐stationary values during initial contact, corresponding to hydrodynamic coalescence process. Consequently, the first stage is defined as the inertia‐dominant stage. In the

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
