Chapter 12. Convective Mass Transfer in Turbulent Flow

Learning Objectives

After completing this chapter, you will be able to:

  • Understand basic properties of turbulent flow and the concept of time averaging.

  • Appreciate that there is a closure problem in modeling of turbulent flows.

  • Define and use the eddy diffusivity model for closure of the problem.

  • Apply the eddy diffusivity model to find the flux and mass transfer coefficients in typical turbulent solid–liquid mass transfer problems.

  • Understand the basis of the analogy of mass transfer with momentum transfer.

  • Understand common models of turbulent mass transfer from a gas–liquid interface.

This chapter introduces and solves problems where mass transfer occurs under turbulent flow conditions. ...
