Abstract
Nonlinear simulations are utilized to investigate the viscous fingering formation in a three-layer radial Hele-Shaw cell. The two interfaces of this system are coupled, and the initial distance between them has a great impact on the interfacial morphologies. This work supplements previous studies, which examined the system via linear and weakly nonlinear analyses.
