## USING PYTHON TO SOLVE CHEMICAL ENGINEERING PROBLEMS

This pdf illustrates how to use the programming language Python to solve the problems posed in the book Introduction to Chemical Engineering Computing, Bruce A. Finlayson, Wiley (2006-2014). The material mirrors the use of MATLAB in the book, and solves … Continue reading

## Error Bounds using the Green’s Function

November 18, 2014 One of the fundamental concepts when solving partial differential equations is the Green’s function. This function allows you to represent the exact solution as an integral. It may be hard to find, and if found, may be … Continue reading

## September 2, 2014 – Numerical Results with Rigorous Error Bounds

Have you ever solved a problem numerically and wondered: How accurate is my answer? Oftentimes the only clue you have is how the solution changes (hopefully not much) as you refine the mesh and solve it with more degrees of … Continue reading

## Source Code for Examples is now Available

July 18, 2014 The source code for all the examples in the book has recently been made available by Wiley. They total 26 MB and can be downloaded by going to booksupport.wiley.com and searching on author: Finlayson (or, title or … Continue reading

April 4, 2014          I’ve added a problem to the website http://www.ChemEComp.com for electrochemical polymerization in a series of stirred tanks. Solutions are given as derived in Excel and MATLAB. It is a simple problem with important insight and comes … Continue reading

## More problems/solutions with error bounds and help integrating in time in Comsol Multiphysics

March 3, 2014 I’ve added some more problems to the website http://www.ChemEComp.com/MWR that goes along with the book pictured above.  Now there are six problems, for eigenvalue problems, boundary value problems in 1D, elliptic boundary value problems, and initial value … Continue reading

## A book in revision and an old book resurfaces!

January 15, 2014 I have revised the material in Introduction to Chemical Engineering Computing to be consistent with AspenPlus 8. The interface looks different when you start, but the ultimate windows where you define the problem are the same. It … Continue reading

## Introduction to Chemical Engineering

September 7, 2013 I have been updating the material on use of Aspen Plus to include version 8.0-8.2. The way you get to the various windows is somewhat different, although most of the operating windows look very similar. Thus, some … Continue reading
