Subject aims expressed by acquired skills and competences

- to demonstrate the feature of criteria of similarity, - to solve the pressure losses during the flow of fluids, - to describe the fundamental principle in hydromechanics, - to solve simple examples focused on heat transfer (conduction, convection, radiation).

Teaching methods

Individual consultations


Theory of similarity, criterion equations. Flow: statics and dynamics of fluids, flow of real fluids, pressure losses, flow of gases in furnace systems. Conduction heat transfer: analytical and numerical solution of steady and unsteady problems. Convection heat transfer: natural, forced, heat transfer between fluid and solid body. Radiation heat transfer: general laws, radiation properties of bodies, exchange of radiation energy between solid bodies, radiation of gases, vapours and their mixtures.
