+Droplet collision occurs frequently in many natural and industrial processes, for example, the formation of raindrops, spray and atomisation. This problem 
+can be characterised by a dimensionless number, the <i>Weber</i> number. Experimental studies on the head-on collision of droplets of equal size have 
+identified four distinct outcomes with increasing values of <i> We </i> number: 1) coalescence after minor deformation; 2) bouncing; 3) coalescence after large
+deformation; and 4) coalescence followed by separation with the generation of secondary droplets. We are interestd in the determining force from regime 1) and regime 2).

-In multiphase flows, the key factor is the presence of an interface separating different phases. Many physical properties, for example density and viscosity, are discontinuous across the interface. The interface also possesses localised properties including the interfacial tension. Furthermore, owing to the fact that the interface is a moving boundary, the evolution of the interface is coupled with the velocity field and pressure, and all of these must be determined simultaneously

 We adopted an approach to track the interface explicitly on a unstructured triangular mesh. An adaptive moving mesh generator was developped to follow the interface evolution and to constanly refine/coarse the compuational mesh. In general, finer mesh is required near the interface as interfacial tension is the driving force in problems we interested in. Applying a coarser mesh in regions far away from the interface also reduces the computing costs.
