Numerical Methods for Chemical Engineering: Solving CSTR Equations

Chemical engineering systems often rely on complex, non-linear equations that cannot be solved by hand. Mastering the numerical methods to model these systems is essential for designing efficient reactors and chemical processes. This text-only course guides you through the foundational principles of chemical reactor modeling, focusing on the Continuous Stirred-Tank Reactor (CSTR) at steady state. You will transition from understanding core thermodynamic and mass balance equations to implementing numerical algorithms that solve non-linear algebraic systems. What you'll learn: - Learn the fundamental mass and energy balance equations governing a CSTR. - Understand how steady-state reactor behavior translates into systems of non-linear algebraic equations. - Apply numerical root-finding algorithms, such as the Newton-Raphson method, to solve reactor equations. - Practice translating chemical engineering problems into structured, readable computational code. - Analyze reactor stability, multiple steady states, and parameter sensitivity through numerical analysis. - Master modern code organization and structured data representations for scientific computing. You will start by exploring the core definitions of chemical kinetics and reactor design before diving into numerical solvers. Through written explanations, step-by-step mathematical derivations, and structured code exercises, you will build a solid foundation in computational chemical engineering. This course is designed for chemistry students, aspiring chemical engineers, and programmers interested in scientific computing. No advanced numerical analysis experience is required, though a basic understanding of algebra and introductory programming concepts is helpful.
