Many systems require very high heat removal rates in small areas due to the increase in
their packing density, such as power electronics. These systems need to be cooled to …

The cooling of a surface can be achieved by the impingement of spray, which is a free
surface flow of droplets ejected from a spray nozzle. Spray cooling can provide uniform …

In pool boiling on a horizontal surface, the flow of vapor is mainly the departure of vapor
bubbles from the boiling surface. If the surface is composed of specially laid-out areas with …

Multi-droplet impact on a liquid/vapor two-phase thin liquid film covering a heated wall is
numerically studied using a three-dimensional model with an implement of a random …

Droplet impact on both dry and wet surfaces is present in several applications, and often
multiple droplets, instead of one single droplet, are involved. This paper focuses on the …

The unpredictable spray characterization caused by different manufacturing standards still
limits the implementation of spray cooling. To obtain a predictable spray, a droplet generator …

Smooth and laser-ablated silicon surfaces with wettability ranging from SHI (super-
hydrophilic) to SHO (super-hydrophobic) are tested in subcooled pool boiling of water. The …

The impingement of ethanol droplet train on the heated titanium substrates without or with
the titanium oxide nanotube coating has been experimentally investigated in close view. The …

Analyzing the impact of a droplet on a liquid film is a typical free-surface problem. However,
a few studies have investigated the impact of multiple droplets, and in most cases, the …

In the process of oil-gas micro lubrication, affected by high pressure, temperature and other
factors, part of the air in the transportation pipeline will be mixed into the oil liquid or part of …
