Experimental investigation of coalescence and breakup of droplets on solid surfaces – Generic config-uration sessile drop (A02)

A02重点研究了通用构型液滴，用于研究液滴在高时间和空间分辨率下合并和破裂的动态过程。具有剪切速率相关粘度或粘弹性性质的流体以及混合物被考虑。基材的光谱被扩展到可膨胀和纳米结构涂层的表面，以及具有图案化的润湿和去湿特性的表面。此外，还应用温度梯度来研究热传递过程中的聚结和破裂行为。

A02 focuses on the generic configuration droplets, which is used to investigate dynamic processes during the coalescence and breakup of droplets with high temporal and spatial resolution. Fluids with shear rate dependent viscosity or visco-elastic properties as well as mixtures are considered. The spectrum of substrates is extended to swellable and nanostructure-coated surfaces as well as to surfaces with patterned wetting and dewetting properties. In addition, temperature gradients are applied in order to study the coalescence and breakup behavior during heat transport.
