I'm a licensed electrical and professional engineer with over six years of specialized experience in MATLAB coding, numerical simulations, and nonlinear systems analysis, and I will develop comprehensive numerical simulations and analytical models to investigate nonlinear resonance phenomena in gravity-driven viscous films over undulated substrates, revealing harmonic generation, bistable resonance, and Duffing-type behavior. Throughout my career, I've implemented numerical solutions for nonlinear partial differential equations, multi-physics simulations involving fluid dynamics and surface interactions, and bifurcation analysis for systems exhibiting resonance and instability. I understand that gravity-driven viscous film flow over undulated substrates involves coupled nonlinear equations governing film thickness evolution, surface tension effects, viscous dissipation, and substrate-induced perturbations. I will formulate the governing equations using lubrication theory approximations, implement numerical solvers in MATLAB or Python using finite difference, spectral methods, or adaptive time-stepping schemes. I will develop analytical models using perturbation methods and multiple-scale analysis to predict resonance conditions, derive amplitude equations revealing Duffing-type nonlinearity with cubic stiffness terms, and identify parameter regimes exhibiting bistability Deliverables will include fully commented MATLAB or Python code.
