#### Aims

To introduce the concepts and definitions of energy, heat and work, to provide the core knowledge and skills to understand and analyse Engineering Thermofluid systems, based on conservation of mass, momentum and energy.

#### Outline Of Syllabus

Fluid Dynamics

Units, dimensions and measurements; density and specific volume; stress in a fluid.

Fluid statics: pressure measurement, manometry,. buoyancy, stability.

Nature of fluids: shear rate and viscosity: Newtonian Fluid and non-Newtonian fluid properties.

Concept of control volume and conservation principles based on Reynolds transport principles.

Nature of flows: ideal flow, steady flow, uniform flow, streamlines, pathlines and streaklines

Conservation of mass: continuity equation,

Conservation of energy: Bernoulli equation (applications for inviscid, incompressible and steady flows)

Flow measurement (orifice plate, venturi, weirs) with data analysis/error analysis considerations.

Conservation of momentum for steady flow.

Thermodynamics

Basic properties (pressure, temperature); equation of state for perfect gas; calorimetry; specific heat capacities;

First Law of Thermodynamics; Steady flow energy conservation equation applied to thermal systems.

Process paths, quasi-static work and heat transfer, isothermal, adiabatic and polytropic processes.

Real substances, Steady flow energy equation applied to steam systems.

First law analysis of cyclic processes: Carnot cycle, cycle efficiency, and air standard cycles (e.g. Otto, Diesel, dual and gas turbine cycles).

##### Teaching Rationale And Relationship

A blended delivery approach is used to provide an easy and accessible way for students to assimilate the knowledge content and convey the underlying engineering science while allowing students to develop the required skills in applying this to discipline-specific engineering problems. This approach comprises:

-Structured guided learning in the form of recorded lectures, animations and notes for delivery of the detail of fundamental concepts and theory;

-Lectures & example classes to go through elements of the material requiring a dynamic and discursive delivery style (e.g. worked examples & problem solving)

-Tutorial questions are provided in NUMBAS to support the students' self-study in reading around the lecture material and developing skills in applying the taught material [skills practice] - learning to solve practical engineering problems. Worked solutions are provided for all tutorial sheet questions in NUMBAS, combined with randomised numbers, will provide the opportunity for repeated practise with instant feedback. Students are encouraged to reflect on their skills practice [reflective learning activity] and prepare to get specific assistance and feedback with these practice questions at the tutorials.

-Six practical laboratory experiments allow students to gain hands-on experience of experimental facilities and techniques used for analysing and solving real engineering problems and reinforce the taught principles and theory in the identified topics.

-The independent study time is essential for students to work through the material, supported with reading, notetaking and tutorial question practice in their own time and at their own pace. Some of this time is allocated for revising for and completing the assessments.

##### Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

##### Assessment Rationale And Relationship

The continual in-course formative assessment will closely follow the NUMBAS-based tutorial sheets, and allow students to become familiar with the online assessment framework, build confidence in answering technical numerical questions, and receive feedback on their understanding. This experience will be carried forward to the in-course summative assessment, which will follow the same approach (M1-3). Similarly, the laboratory assessments will be comprised of short NUMBAS-based questions based on the practical sessions designed to test understanding of the physical experiments.

The end-of-year examination will follow a similar approach to the in-course assessment, but will also provide an appropriate way to assess both theoretical understanding and practical problem solving skills under time-constraint as required in industry, and will be composed of all material covered during the module.

A single A4 sheet (two-sided) may be prepared in advance and taken into the exam as a study support with access to teaching materials on Canvas.
