MECH8007 - Fluid Dynamics

Title:Fluid Dynamics
Long Title:Fluid Dynamics
Module Code:MECH8007
Duration:1 Semester
Credits: 5
NFQ Level:Advanced
Field of Study: Mechanical Engineering
Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 2 programme(s)
Module Coordinator: GER KELLY
Module Author: GER KELLY
Module Description: This module will introduce the students to dimensional analysis and similarity and their application to problems in fluid mechanics and in particular rotodynamic machines. The development of laminar and turbulent boundary layers is described leading to computation of drag forces.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Employ dimensional analysis techniques based on the indical or buckingham PI method to deduce the fundamental relationships between different variables in Fluid Mechanics problems
LO2 Explain the significance of common dimensionless groups and their relevance and application to similarity and modelling.
LO3 Derive or apply the euler head equation for flow through to rotodynamic machines
LO4 Derive centrifugal pump dimensionless numbers and or be able to apply these to evaluate the effect of changing parameters such as pump impeller speed or size on pump characteristics
LO5 Describe the formation of a boundary layer and apply equations for computation of layer thickness and velocity profiles within the boundary layer.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Co-requisite Modules

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
