Subject fundamentals
The aim of the course is to give the basic knowledge of fluid properties of compressible and incompressible fluids and their behavior. The elementary tools to solve some fluid problems are given: computation of forces both in static and dynamic conditions and the analysis of fluid motion through pipelines.
Expected learning outcomes
Upon completion of this course, students should be able to:
• Articulate the properties that distinguish fluids from other forms of matter, and the broad range of engineering applications which involve fluid mechanics.
• Apply the concepts of vector fields (velocity, force acceleration), scalar fields (pressure, density, temperature), and vector differential and integral calculus to engineering analysis of fluids systems, and to the interpretation of flow physics through the conservation laws.
• Properly apply Newton's second law to analysis and design involving fluids at rest using integral and differential calculus, including pressure variation, forces and moments on plane surfaces, and buoyancy.
• Properly apply systems and control volume methods based on mass, momentum, and energy conservation, as appropriate, to the analysis and design of engineering fluids systems.
• Correctly interpret and apply the various differential forms of the conservation laws, particularly Newton's law and its various approximate forms, to engineering analysis and design.
• Properly apply mass, momentum, and energy conservation to steady internal (pipe) flows, correctly interpret and apply laminar and turbulent flow models, and estimate head loss and power requirements in piping systems.
• Develop mathematical models through justifiable approximations, correctly interpret and apply the "inviscid" approximation and the "Bernoulli" relationships to analysis of fluid systems, and estimate levels of approximation in engineering models.
• Apply integral methods, and basic empirical and theoretical models, to the analysis of boundary layer flows, and to drag on bodies.
• Apply fundamental knowledge of fluid mechanics to the analysis of specific sensors and instruments used in fluid-flow experiments.
Prerequisites / Assumed knowledge
Knowledge of calculus (differential equations, integrals) and the concepts of physics related to mechanics.
Contents
This course is an introduction to fluid mechanics, and emphasizes fundamental concepts and problem-solving techniques.
Topics to be covered include fluid properties, fluid statics, fluid kinematics, control volume analysis, internal flows (pipe flows), differential analysis (including approximations such as creeping flow, potential flow, and boundary layers), and external flows (lift and drag).
If time permits, brief introductions to computational fluid dynamics (CFD) and turbo machinery (pumps and turbines) will be provided.
Students are also expected to be proficient in applying mathematics (e.g., integration, differentiation, and differential equations), statics and dynamics (e.g., free body diagrams), and thermodynamics (e.g., the first law).
Delivery modes
The course is divided in lectures and applied lectures. The applied lectures consist of exercises aimed to further deepen the understanding of the concepts presented in the lectures.
