Section Description

Fluid pressure distributions; integral control volume systems; differential relations for a fluid particle; dimensional similarity; viscous flow in ducts; boundary layers; inviscid incompressible flows. Topics • Introduction: Concept of a fluid, Continuum hypothesis, dimensions & units, fluid properties, viscosity, surface tension, Reynolds number, Rotational vs. Irrotational Flows, Vorticity • Pressure distribution in fluids, manometers, hydrostatics, buoyancy and stability • Control volume analysis (integral form), conservation principles, the Bernoulli equation • Differential relations of fluid motion, conservation equations, Navier-Stokes equation, boundary conditions, stream function, vorticity, potential flows • Dimensional analysis, the Pi theorem, dimensionless numbers, design of experiments • Internal flow, viscous flow in pipes, fully developed laminar vs. turbulent flow • External flow, Reynolds number effects, boundary layer effects, lift-drag on airfoils • An introduction to CFD, compressible flow, open-channel flow

Section Expectation

Academic Integrity Academic dishonesty will not be tolerated. This course shall be in accordance with the University of Vermont’s Code of Academic Integrity as defined by the Center for Student Ethics and Standards. http://www.uvm.edu/cses/ Course Pedagogy Importance of Homework: Solving engineering fluids problems is the only way to understand and master the topic. Thus, homework is an important part of this class. Solutions to the homework will be posted soon after the due date and/or given in class. For these reasons, homework submitted after the due date will receive a severe grading penalty. Cooperative Work: You are encouraged to discuss the homework problems with classmates; however, the final work you turn in must be your own. Copying someone else’s work is unacceptable. You are encouraged to help each other understand the concepts and problem solving techniques involved. There is a clear distinction between discussing work and copying someone else’s work. If you simply copy what someone else has done, you are not increasing your understanding of the material. It is very easy to recognize copying. Presentation: Sloppy, untidy submission of work will be penalized for two main reasons. First, it is not the responsibility of the grader to attempt to decipher your solution because it is either hardly readable or disorganized. Second, as a potential professional engineer, it is important that you learn to communicate your work in the most professional manner possible. This includes the presentation of plots, charts, graphs, figures, equations, and short essays. Website: The UVM blackboard will be used primarily for posting assignments, solutions, and information communicated to the class via UVM’s email system.
