Biosciences and engineering implies an   in depth  understanding of fluid dynamics and transfer of  heat and mass transfer in complex systems such as  agricultural soils, living organisms, plants, natural environmental systems, bioreactors,  chemical reactor chains,  etc.

The course covers the basic principles of fluid mechanics and thermodynamics. After introducing the physical and thermodynamic theory, operational equations are presented to solve simple problems in fluid mechanics and mass transfer and energy.

These equations support the design of many devices operated by bio-scientists and bio-engineers such as hydraulic circuits, machines,  hydraulic and pressure measurement systems, pumps, heat exchangers, air conditioning systems, '

At the end of the course and practical work, students will be able to:

·       Understand the laws of conservation of mass, momentum and energy based on principles of fluid mechanics and thermodynamics;

·        Develop mathematical formulations to describe the transfer of mass and energy in specific environments for the bio-engineer, under transient and steady states and for simple operational conditions (boundary conditions);

·       Calculate mass transfer and energy for  simple problems specific to the domain of the  bio-engineer;

·        Describe the principles of certain technologies associated with heat or momentum or mass transfer as for instance,  pumps, heat exchangers, air-conditioning systems;

·        Describe the principle of measurement techniques like i.e. the measurement of flow and pressure in hydraulic circuit, the measurement of moist air variables;

·       Address various applications of mass transfer and energy, with a basic modeling knowledge of phenomena like conduction, convection, radiation, turbulence, diffusion, evaporation, etc..
