TOTAL STUDENT WORKLOAD




Students are required to attend and participate in all the formal timetabled sessions for
the unit. Students are also expected to manage their directed learning and independent
study in support of the unit.


Whe
re normal timetabled sessions do not take place, additional directed learning may be
provided, and/or students are expected to undertake additional independent learning.


PREREQUISITES


A course of study equivalent to Mathematics Level 4.


UNIT DESCRIPTIO
N


This unit provides the basic principles of thermodynamics, and deals with the generation
of heat, the transfer of heat and the laws of transformation of heat into other forms of
energy. The needs of modern sea transport have given rise to complex marine

thermal
plant, such as turbines, compressors, reciprocating engines, boilers, condensers,
refrigerators and heat pumps. Each of these items makes use of the behaviour of a fluid as
it is heated, cooled and expanded, and compressed. The design and energy e
fficient
operation of such plant requires an understanding of the energy laws.

AREAS OF STUDY


Thermodynamic systems:

Thermodynamic system, open/closed system, conservation of

energy and 1
st

law, enthalpy (h = u + pV), Non
-
flow energy equation (Q
-

W = U), steady
-
f
low energy equation (Q
-

W = H + KE).


Thermodynamic processes:

Boyle’s, Charles’ law and combined law, equation of state,
characteristic equation, relationship p, V and T for polytropic and adiabatic case,
(constant volume/pressure, isothermal, adiabat
ic), work and heat transfer, specific heat
(C

, C
V
), relationship between C
P
, C
V
, R.


Steam processes:

Property tables, terms, interpolation, boiler efficiency, equivalent
evaporation, throttling, entropy.


Combustion:

Solid, liquid and gaseous fuels, equ
ations of combustion by mass and volume,
stiochiometric and actual air requirements, flue gas analysis by mass and volume, HCV and
LCV.


Heat transfer:

Conductive HT through composite wall, HT through composite thick
cylinders, boundary layer film coeffic
ients, surface HT coefficients, overall HT coefficient
‘U’. Radiation.


LEARNING AND TEACHING STRATEGY


A series of structured lectures introduce the theoretical concepts of the unit. This is
complemented by the use of a series of tutorial sheets in smal
l group sessions to apply the
theory to problem solving, allowing students to identify solutions to thermodynamic
systems and processes.

ASSESSMENT STRATEGY


In order to assist the students learning, the coursework assessment process is designed to
provide feedb
ack of a regular and formative nature. The tutorial sheets, used in the small
group teaching sessions, and the coursewo
rk assignment (AE2
) both provide opportunities
for formative feedback. The assignment is designed to assess learning outcomes 3 and 4,
a
nd the examination, learning outcomes 1 and 2.
