1 Introduction

The droplet collision is an important phenomenon that can be seen in nature, such as atmospheric raindrop formation, spray characteristic, etc. In the process of spray formation, distributions of droplet size can be affected by the collision angle and the relative velocity of the droplet collision. Recently, the process of spray formation is used frequently in a lot of industrial ...
