This unit is broadly divided into two interrelated strands. One strand on modelling in general uses mathematical tools developed so far to model a variety of situations. It develops the importance of dimensional analysis and similarity solutions. This strand is project based. The other strand further develops the modelling of fluid dynamics by presenting basic Newtonian viscous fluid flow. Revises some of the second year work and develops further to viscous flow. Applications to slow flows and to similarity solutions in fast flows are also developed.
