A model has been developed to describe the collision and possible coalescenceof two driven deformable drops in the Hele-Shaw cell. The interdependencebetween hydrodynamic effects and interfacial deformations is characterised by afilm capillary number: Ca_f = (\mu v/\sigma)(R_o/h_o)^(3/2) as revealed by ananalytic perturbation solution of the governing equations for a system withcontinuous phase viscosity \mu, interfacial tension \sigma, drop radius R_o,characteristic relative velocity v and separation h_o between the drops.Numerical solutions of the model demonstrate the importance of the full dynamichistory of the interacting drops in determining stability or coalescence. Thegeometry of the Hele-Shaw cell allows for the possibility of using the model toinfer the time dependent force between colliding drops by measuring theirseparation.
