Mass Transfer Processes: Modeling, Computations, and Design

Chapter 1. Introduction to Modeling of Mass Transfer Processes

Learning Objectives

After completing this chapter, you will be able to:

• Explain the role of modeling of mass transfer processes in a variety of diverse fields.

• Understand the steps needed in modeling of a given system or equipment involving mass transfer.

• Define control volume and mark its bounding control surface.

• Write a species conservation law (mass balance) first in words and then as a mathematical equation for the chosen control volume.

• Distinguish three hierarchical levels of models—that is, differential, macroscopic, and mesoscopic models—depending on the size of the control volume chosen.

• Identify the closure relations needed in addition to species mass balance to complete ...
