Unsteady Heat Flow in a Slab – Simple Parabolic Partial Differential Equation (PDE)

Reference: This is from E.M. Rosen and R. N. Adams, “A Review of Spreadsheet Usage in Chemical Engineering Calculations”, Computers and Chemical Engineering, Vol. 11, No. 6, pp. 723-736, but they took it from Carnahan, Luther and Wilkes, “Applied Numerical Methods”, Wiley NY 1969 pg 434.  Very similar to an earlier problem that we did […]

Solving a Binary Batch Distillation – Programming Approach

Plan your solution: Draw a picture, in this case, list all of your data Remember the fundamentals and apply Draw your material or energy balance envelope (If necessary, list out your equations and problem data) Remember [Accumulation = In – Out + Source/Sink] Think about what you need to do and the answer you want […]
