To solve the title problem, we use the differential-algebraic equation system approach where robust adaptive timestepping algorithms are available in the solvers, e.g., RADAU5 and DASSL. Mathematical and numerical models for coupled chemical reactions and fluid flow are derived. These models have several interesting properties, e.g., strong nonlinearities and stiffness, which are discussed. We test the performance of our code.
