Course Objectives

  1. This course follows a unified approach to introduce the physical origins and rate equations of heat and mass transfer. The principal topics covered include identification of the driving forces for heat and mass diffusion, development of transport models from first principles, steady state and transient solutions, and convective transfer. The boundary layer analogies are introduced. Closed form analytical solutions and correlations derived from dimensional analysis are used to estimate the heat and mass transfer convection coefficients
  2. To be thorough with knowledge of various chemical engineering separation processes.
  3. Ability to Select appropriate separation technique for intended problem.
  4. Ability to analyze the separation system for multi-component mixtures. Ability to design separation system for the effective solution of intended problem.

Course Outcomes

1. Identification of mechanisms of heat and mass transfer.
2. Development of transport models based on the differential equations of heat and mass transfer and their simplified forms identification of suitable boundary conditions.
3. Solutions of the differential equations for steady-state, one-dimensional problems solutions for non-steady state problems.
4. Estimation of heat and mass transfer coefficients based on dimensional analysis, boundary layer analysis and similarity between momentum, heat and mass transfer.
5. Solution of problems involving convective heat and mass transfer in one phase and two phase systems.
