# FLUID MECHANICS & THERMODYNAMICS - 2024/5

Module code: ENG1089

## Module Overview

First year common module in thermo-fluids for MES + Chemical Engineering students.

FLUID MECHANICS: The basic concepts underlying fluid flows and behaviour are described together with simple fluid properties. The calculation of static fluid forces is the starting point before moving to dynamic fluid effects including mass-flow and energy conservation. Non-dimensional analysis methods, laminar and turbulent flows and pipe system analysis are considered, including fluid friction, momentum and energy losses in fittings.

THERMODYNAMICS:  Following an introduction on energy consumption, generation and supply from conventional and alternative sources the basic principles of heat and work transfer are described and system thermal efficiency. Thermal properties of working fluids (both liquids and gases) are described. The 1st law of thermodynamics is introduced with applications to processes and cycles for closed and steady-flow systems.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes in the final examination. The mini-project tests research skills and report writing as well as their ability to record a simple experiment and comment critically on accuracy and methods employed.

Thus, the summative assessment for this module consists of:

• Thermodynamics Coursework  [ Learning outcomes 3, 5 ]                   {35%}

• Examination               [ Learning outcomes 1, 2, 3, 4 ]         (2 hours)   {65%}

For the Thermodynamics coursework, the students will be able to work in a group and discuss, but will need to submit an individual assignment.

For exam preparation, a series of targeted sessions will be scheduled that are specifically designed to prepare students for examination. This will include revision lectures that summarize key module content, clarify complex topics, and highlight areas frequently tested in examinations. These lectures will be informed by an analysis of previous exam results and will include questions from previous exam papers, to ensure they are precisely aligned with the most challenging aspects of the course materials. Before the final exam, additional contact hours will be offered for one-on-one consultations to ensure that students can receive personalized guidance on exam techniques.

Formative assessment and feedback

• Formative verbal feedback is given in tutorials

• Formative Multiple Choice Tests are available on SurreyLearn to give feedback on understanding of simple principles

• Written feedback is given on the coursework assessments including a TurnItIn report on their Thermo mini-project

## Module aims

• • an introduction to fluid mechanics and thermodynamics and in particular internal flow behaviour and the principles and methodologies applied to fluid statics, dynamics and 1st law thermodynamics
• • an understanding of the principles of energy generation, conservation, conversion and alternative energy sources

## Methods of Teaching / Learning

The learning and teaching strategy is designed to:

introduce thermo-fluid principles through theory with worked examples. This is delivered principally through lectures and tutorial classes and concludes with an independently conducted mini project involving basic experimental procedures.

The learning and teaching methods include:

• Lectures

• Tutorials

• Independent learning

• Thermo mini project submitted on SurreyLearn

• Additional support for preparation towards the exam, which will include dedicated lectures for solving past exam papers and revision of the entire FM component.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

## Other information

 The School of Chemistry and Chemical Engineering is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas: Digital Capabilities: Throughout the programme students learn to navigate and utilise the Virtual Learning Environment @ Surrey (SurreyLearn) and other digital resources and online databases to aid their learning and undertake research. Students are encouraged to use current media such as WhatsApp, Teams, Zoom, and utilise cloud/file sharing for communication and team working in the Thermodynamics group coursework. Employability: The topics covered in this module such as fundamental concepts related to laminar and turbulent flows, functioning of pumps and turbines, laws of thermodynamics, etc., are specifically chosen to equip students with knowledge and skills that are key to the role of chemical engineers. The two pieces of coursework undertaken in this module help students in developing the ability to critically appraise evidence and the appropriate application of this knowledge to ascertain the flow and thermal behaviour of fluids. This helps imbibe  critical thinking, problem-solving and analytical skills among students. Sustainability: This module provides basic understanding of thermodynamics that can help students to gain knowledge on improving the efficiency of reactions and improving process efficiency. Resourcefulness and Resilience: This module requires practical problem-solving skills in both tutorials and coursework that teach students how to reason about, and solve, new unseen problems starting with a problem scenario and designing and developing a complex and practical solution to the problem. Thermodynamics group coursework helps students in learning skills related to teamwork, managing of timelines, and communication.
