The unit aims to:
Provide an introduction to the methods of integration and solution of ordinary differential equation systems arising from the mathematical modelling of chemical engineering applications.
First-, second- and higher-order ordinary differential equations. Role of initial and boundary conditions.
A range of solutions to first-order differential equations will be covered with and without constant coefficients including separation of variables, linear differential equations, Bernouilli differential equations, homogeneous differential equations and differential equations solvable for x or y.
Then solutions to second- and higher-order differential equations will focus on differential equations with y or x missing, linear differential equations with constant coefficients, reduction of an order technique, the inverse operator technique, the Cauchy/Euler equation,
Partial differential equations. Characterization of solutions. Separation of variables technique of solving partial differential equations.
Application of differential equations to Physical and Chemical Engineering examples.
Double and triple integrals and their applications for calculating surface areas and volumes. Cartesian, polar and spherical coordinates. Converting integrals from Cartesian to polar or spherical coordinates.
Vector algebra. Scalar and vector fields. Scalar and vector products of vectors. Vector calculus.
Gradient, divergence and curl operators. Gauss’s theorem. Green’s theorem.
Teaching and learning methods
A combination of 16 lectures and 8 interactive workshops (problem solving sessions).
In addition, podcasts of the lectures will be available on Blackboard.
Lecture notes with additional problems and exercises will be available from Blackboard.
Worked-out answers of the problem solving sessions will be provided afterwards via Blackboard.
