Solving BVODEs

This is the first video in the Solving BVODEs Supplement to SCoRE, a Self-Study Course on Reaction Engineering (https://buffalobadger.github.io/SCoRE/). SCoRE is based on the online book, “Reaction Engineering Basics” (https://buffalobadger.github.io/RE_Basics/). Analyzing a reactor with axial dispersion requires the solution of a set of boundary value ordinary differential equations, or BVODEs. In SCoRE and Reaction Engineering Basics they are always solved numerically, so its important to know how to solve them. 0:00 Intro 0:28 Overview 1:36 BVODE Solver Input 2:39 The Derivatives Function 3:39 The Boundary Conditions Residuals Function 4:49 How BVODE Solvers Work 6:39 BVODE Solver Issues and Return Values 8:05 Formulation of the Calculations for Solving BVODEs 10:53 Example Formulation 11:55 Solving BVODEs Summary I hope you found this video to be informative.
