The module “Fluid Mechanics &Heat Transfer” aims at learning to understand and being able to apply the disciplines of fluid mechanics and heat transfer in view of engineering problems. The module consists of three courses:
• Fluid Mechanics 1
• Heat Transfer
• Fluids Engineering (project)
Fluid Mechanics 1
Fluid mechanics is the discipline that describes the dynamics and mechanics of fluids (liquids and gases). Many applications are involved, such as computing forces on airplanes, determining the fluid velocity in an injection needle, the effects of a rough sea on the dynamics of a ship, making a wheather forcast or even describing trafic on roads.The purpose of the discipline is to describe characteristic variables such as velocity, density, pressure and temperature as functions of space and time.In the course Fluid Mechanics 1 the integral and differential formulations of the three conservation principles of mass, momentum and energy are derived. Limiting cases such as steady and inviscid flows are discussed. Several applications of the integral formulations are treated such as computing the force on a construction. Fully developed incompressible flows are introduced and the reduced Navier-Stokes equations are derived. Also introduced are the concepts of dimension analysis, similarity and Reynolds number. Subsequently compressible flows are discussed based on a perfect gas modeling. Finally the concepts of total pressure, -density and -temperture are introduced.
In numerous engineering systems, the thermal management of great importance. The course Hesat Transfer addresses the three mechanisms of heat transfer (conduction, convection and radiation) on the basis of practical applications. Because convective heat transfer takes place by means of the flow of gases and liquids, the essential basic phenomena in fluid dynamics are also discussed.
