Aims & Objectives:
To provide the student with basic knowledge, concepts and problems of fluid and solid mechanics necessary for the analysis of blood flow in the macro and microcirculation, and to other physiological flows.
Learning outcomes & Competences:
The students will be able to:
Describe the mechanics of cardiovascular blood flow and apply fluid mechanic flow models to flow in tubes.
Understand physiologically relevant fluid and solid mechanics.
Understand fluid and solid mechanics that are pertinent to blood flow in the heart and blood vessels.
Apply fluid mechanical analyses relevant to biomedical engineering problems.
Conduct fluid mechanical analyses of human circulation, primarily applied to blood flow at the arterial level.
Conduct fluid mechanical analyses of vascular implants (e.g., prosthetic valves) and measurements in the cardiovascular system.
Understand and analyze velocity measurement techniques relevant to blood flow (e.g., MRI, Ultrasound, Doppler).
