Numerical Methods for Chemical Engineering: ODEs and Integration

Chemical engineering relies heavily on mathematical modeling, where physical phenomena are translated into differential equations. To analyze and design chemical processes, engineers must understand how to solve these equations when analytical solutions do not exist. This text-based course guides you through the foundational concepts of solving ordinary differential equations as initial value problems and performing numerical integration. You will transition from understanding basic mathematical theory to implementing robust numerical algorithms that simulate real-world chemical systems. By working through clear explanations and practical code examples, you will gain the skills to model reaction kinetics, mass transfer, and heat transfer processes. What you'll learn: - Understand the foundational theory of ordinary differential equations and initial value problems in chemical engineering - Apply numerical integration techniques to calculate key process variables and system behaviors - Implement Euler's method and Runge-Kutta algorithms to solve dynamic system models - Analyze error propagation and stability criteria to ensure your numerical solutions are accurate and reliable - Practice writing clean, modern Python code using standard scientific libraries to automate complex numerical calculations This course begins with core definitions, mathematical terminology, and the fundamental principles of numerical approximation. You will then progress step-by-step through solving single differential equations, handling systems of coupled equations, and evaluating complex integrals. This structured approach ensures you build a reliable toolkit for engineering analysis. This course is designed for beginners, engineering students, and practicing professionals who want a solid, practical introduction to numerical methods. No prior experience with numerical solvers is required, though a basic understanding of calculus and introductory programming concepts will help you get the most out of the material.
