Courses

Fluid mechanics and transport phenomena

ChE-330

The concept of Shell balances, the Navier-Stokes equations and generalized differential balances equations for heat and mass transport are derived. These relations are applied to model systems. Integral balances are introduced in the context of boundary layers and transfer coefficients.

Numerical methods

ChE-312

This course introduces students to modern computational and mathematical techniques for solving problems in chemistry and chemical engineering. The use of introduced numerical methods will be demonstrated using the Python programming language.
