Abstract:

In this work, we numerically investigate fluid dynamics during simultaneous and non-simultaneous impact of drops on a wall. Our goal is to improve the basic understanding of spray cooling, which is a promising method for cooling electronic components that dissipate heat with high heat flux. We vary the horizontal spacing and time interval between each drop to investigate their influences on the evolution of the wetted area, contact line length and liquid layer. Our study provides valuable insights into the complex fluid dynamics.
