Convection Heat Transfer
Introduction
In the previous chapters, we discussed the
mechanism and calculations of conduction
heat transfer.
Convection was considered only as a boundary
condition for the conduction problem.
In this chapter, we wi
Flow across cylinders and

Flow across cylinders and spheres is important as the
flow inside tubes.
The boundary layer determines the heat transfer
characteristics.

SHELL AND TUBE EXCHANGERS
CONSTRUCTION DETAILS
Advantages of Shell and Tube HEX
The configuration gives a large surface area in a
small volume;
Good mechanical layout: a good shape for
pressure operation;
Uses well-established fabrication techniques;
Effectiveness-NTU method
This method is used when the inlet or outlet
temperatures are needed to be evaluated for
a GIVEN HEX.
The LMTD analysis frequently requires a
iterative solution.
The effectiveness-NTU method is based on the
effectiveness of the
Conduction-Convection systems
and Fins
What are Fins ?
Fins are extended surfaces used to increase
the rate of heat transfer.
It is made of highly conductive materials such
as aluminum.

Heat Exchangers (HEX)
The application of the heat transfer principles
to the design of HEX is extremely important.
Economics play a key role in the design and
selection of HEX.
Weight and size are also important.
Heat exchangers are devices
Flow across tube bank
Because many heat exchanger
arrangements involve multiple row of
tubes, the heat transfer characteristics for
tube banks are of important interest.
Tube arrangements could be of two types:
staggered and in-line

Radiation Heat Transfer
Chapter 8
Introduction
Conduction and convection heat transfer
require the presence of a medium while
radiation does not.
All objects with temperatures above absolute
zero radiate energy.
Energy is transferred by electromagnetic
