学生毕业后能胜任现代火力发电厂
,
制冷与低温工程及相关
的热能与动力工程专业的技术与管理工作
,
并能从事其它能源动

.
The graduates may find employment of
technology and management in the fields of the
Thermal Energy &Power Engineering
(TEPE)
and
its
relevance,
such
as
modern
power
plant
or
the
Refrigeration
and
Cryogenics
Engineering
(RCE),
the
graduates may also engaged in the
special technique in the fields related to TEPE.
现代空气动力学、流体力学、热力学、水力学以及航空航天工
程、水利水电工程、热能工程、流体机械工程都提出了一系列复
杂流动问题
,
其中包括高速流、低速流、管道流、燃烧流、冲击流、振荡流、涡流、湍流
、旋转流、多相流等等
A
series
of
complicated
flow
problems
have
been
posed
in
modern
fluid
mechanics,
aero
dynamics,
thermodynamics,
and
aeronautical
and
aerospace
engineering,
water
conservancy
and
hydropower
engineering,
heat
energy
engineering,
fluid
machinery engineering,
and so on, and they cover high-speed flow, low-
speed flow, eddy flow, turbulent flow, burning
flow,
impact flow, oscillating flow,
backflow, and two-phase flow, etc.
In
the thermal engineering, the studied objects
normally are isolated from one another and then we
try to analysis the change
and interaction, the studied objects
isolated is named thermodynamic system.
在热力工程中，通常将研究对象分离出来再分析其变化及（与外界）的相互作用，该对象即热力系统。
Conduction is a process that
the heat transfers from the parts of high
temperature of the object to the low or from a
warmer
object to the cooler contacting
with it. 2
导热即热量从物体的高温部向低温部或从热物体向与之接触的冷
物体传递的过程。
Thermal convection
may occur from one location to another by means of
current set up in a fluid medium. 4
对流是借助于流体介质形成的介质流来实现热量传递任务的。
For radiant heat transfer, there is a
change in energy form; from internal energy at the
source to e
lectromagnetic energy for
transmission, then back to internal
energy at the receiver. 6
而热
辐射（过程的实现）有一能量形式的转换过程，即热源内能（先）转化为电磁能进行传递，再于接受处转化为内能
形式。
Radiation
is
the
only
type
of
heat
transfer
that
can
travel
through
a
vacuum,
such
as
space,
because
radiation
i
s
not
dependent of matter as a medium of heat
transfer. This is impossible with convection and
conduction because they require
some
form of matter, like air or water, tobe the
transmitting medium.
热辐射是唯一
能够穿透真空（如宇宙空间）的热传递形式，因为热辐射不依赖于介质。这对于热对流和热传导是不可能的
,
因为
它们需要空气和水等热传递介质。
Boiler
A
boiler
is
a
closed
vessel
in
which
water
(or
other
fluid)
is
heated
under
pressure
and
generate
steam,
the
fluid
is
then
circulated out of
theboiler for use in various processes or heating
applications, such as formotive power or to
provide heating
in a house. 1
锅炉是一种闭口容器，水（或其他流体）被加热产生压力蒸汽
，然后循环于锅炉外各种过程或加热应用
，如提供动力和为房间
供热。
Electric
boilers
use
resistance
or
immersion
type
heating
elements.
Nuclear
fission
is
also
used
as
a
heat
source
for
generating
steam.
Heat
recovery
steam
generators
(HRSGs)
use
the
heat
rejected
from
other
processes
such
as
gas
turbines.
电锅炉
使用电阻或浸入式加热元件。原子核裂变也用于产生蒸汽的热源。回热式蒸汽发生器（简称
HRSGs
）是利用其它过程
中排放的热量来工作的，如燃气
轮机中燃气的余热。
The
water-tube
construction
facilitates
obtaining
greater
boiler
capacity,and
the
use
of
higher
pressu
re.
In
addition,
the
water-tube boiler offers greater
versatility in arrangement and it permits the most
efficient use of the furnace,
