Course Objectives

  1. Provide an introduction to individual / simultaneous momentum, energy and mass transport processes.
  2. Teach student how to develop mathematical representation of physical process and get its analytical solution using proper initial and boundary conditions for analysing the system performance.
  3. Help student to understand the analogy among the transport processes.

Course Outcomes

Doing this course
1) Students will understand the modelling technique of mass, momentum and energy transport problems.
2) Students can select proper boundary conditions to solve the partial differential equations which represent the physical system.
3) Students will be able to analyse input-output data of the transport processes.
