This paper describes experimental and numerical work relevant to the impact of single and multiple drops onto various solid substrates. The experimental methods are based on visualization techniques and the single drop spreading transients are obtained using the variational principle and a commercial numerical code. The collision of two drops is then considered and the results lead to a simple model able to describe the axisymmetric collision of drops. The extension of the model to other forms of coalescence is also discussed.
