Software Evaluation Via a Study of Deviations in Results of Manual and Computer-Based Step-Wise Method Calculations for Shell and Tube Heat Exchangers

In this study manual calculation for both shell and tube, sides of a single-phase shell and tube heat exchanger are conducted. The calculations are made using Aspen B JAC software, results of step-wise method computations are compared with manual calculations. Results show that although more accurate methods like step-wise method include many details in calculations, difference between the yielded results and experimental-based algorithms like Bell Delaware's method is acceptable.
