Virtually all energy engineering applications involve flowing fluids. This is the case for heat transfer in heat exchangers used in various sectors of industry, housing, etc. It is also the case for all heat engines (reciprocating internal combustion engines, steam turbines, gas turbines, turbojets, etc.). This also applies to all heat engines (reciprocating internal combustion engines, steam turbines, gas turbines, turbojets), hydraulic turbines, pumps, refrigeration machines, furnaces, boilers, etc.
Engineers working on these applications need to have a thorough understanding of the physics and mechanics of fluid flow. The articles that follow aim to provide this fundamental knowledge for the successful implementation of energy systems.
