##### Introductory description

ES2C5-15 Dynamics and Fluid Mechanics

##### Module aims

The principal aims of the module are to develop upon a firm understanding of mechanical concepts from the first year. Furthermore the module aims to generate a familiarity with key techniques used in the analysis and testing of mechanical systems, and then to introduce fundamental concepts underpinning solid and fluid dynamics.

##### Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

The module is delivered in two parts: Dynamics and Fluid Mechanics. The topics covered are:
Dynamics

• The principles of work and energy (potential energy, conservative and non-conservative forces)
• Analysis of rigid-body motion: kinematics and kinetics.
• Analysis of standard mechanisms: slider-crank, four bar link.
• Deriving governing equations for general systems using energy methods.
• Step response and frequency response of second-order systems: oscillation, vibration and resonance.
• Supporting laboratory exercises.

Fluid Mechanics

• Viscosity: real and inviscid fluids
• Pressure and its measurement (manometers)
• Reynolds number: laminar and turbulent flow
• Conservation of mass and momentum (the continuity and momentum equations).
• Application of Bernoulli's equation
• Model testing, dimensional analysis, and drag coefficients
• Laminar and turbulent flows; pipe flows, surface roughness, Moody Chart.
• Compressibility effects.
• The role of pressure in fluid mechanics and the 1-D wave equation for an acoustic wave.
• Supporting laboratories in wind-tunnel measurement of flow around a cylinder, and internal flow in a converging/diverging pipe.

The above topics will be augmented with deeper teaching of the practical applications of mathematical methods. Methods used will include vector calculus, linear algebra, differential and partial differential equation solutions.

##### Learning outcomes

By the end of the module, students should be able to:

• Analyse rigid body planar motion. Understand that forces maybe either conservative or non-conservative and appreciate how these apply in modelling real-world applications.
• Employ the principles of work and energy as a means to generate governing equations and evaluate system response.
• Perform kinematic and kinetic analysis of rigid bodies employing vector methods and graphical solutions as appropriate.
• Demonstrate knowledge and understanding of the well-established equations of fluid mechanics and be able to classify different types of flow regime and fluid behaviour using appropriate dimensionless numbers.
• Apply Bernoulli’s principle to a range of applications to predict inviscid fluid-flow behaviour, while being able to identify its limitations. Show appreciation for extensions to fluid mechanics theory, e.g. compressibility, surface tension.
• Analyse experimental measurements of velocity and pressure, and be able to quantify and analyse the various forms of error.
