Book Description
Droplet evaporation and the resultant patterns provide a fundamental understanding of deposition of multiscale particles suspended in solutions. One of the significant applications of studying evaporative patterns is the inkjet printing which is deemed as an ideal method for deposition of conductive nanomaterials for the fabrication of flexible device. This work examines the drying pattern of manganese oxide droplets post evaporation. A variety of governing parameters such as substrate temperature, substrate wettability, surface tension and particle concentration were investigated. It was observed that both hydrophobic and hydrophilic substrates maintained at room temperature rendered coffee-rings with uniform distribution of particles at both low and high concentrations. Similar coffee rings patterns were formed on hydrophilic substrates and base fluid comprising of 90/10 (DI water/ethanol). However, on hydrophobic surfaces, rings with an inner deposit of particles were obtained. Additionally, the patterns observed with both hydrophobic and hydrophilic surfaces heated at 50° C resulted showed predominantly ring-like patterns with uniform distribution of particles with the only difference being the variation in ring thickness.

Book Description
This report summarises results of the coalscence efficiency of colliding drops which were obtained from laboratory experiments and a theoretical model. Both theory and experiment suggest that the coalescence efficiency is a function of both drop radii and drop size ratio. Even though no clear dependence of coalescence efficiency on impact speed was observed experimentally, the theory does predict some dependence on velocity. Generally it is observed that the coalescence efficiency decreases with increase in the size of the large drop, R(L), and the drop size ratio, p. However, for small R(L) a decrease in the efficiency was also shown. Both theory and experiment demonstrate the strong dependence of coalescence on impact angle. From the experiments two empirical equations were obtained which relate the coalescence efficiencies and partial coalescence efficiencies with p and R(L). These could be used in numerical models of cloud and rain development. (Author).
