Abstract
This literature review presents the extensive literature survey of various heat exchangers (HEs) for the design optimization
using advanced optimization techniques concerning with various aspects. The chief objective of this work is to focus on the
parametric design optimization of different types of HEs using advanced optimization algorithms and therefore only the
research works associated with advanced optimization techniques are considered. This is the first paper which exclusively
summaries the research works concerning with the parameter optimization of HEs using advanced optimization techniques.
Various types of HEs considered in this review paper are shell-and-tube HEs, plate-fin HEs, fin-tube HEs and various configu-
rations of HE networks etc. The parametric design optimization of HEs is associated with number of structural and physical
parameters having highly complexity. Trial and error method is used in the general design approaches and this becomes
tediously and time consuming and not having the guarantee of getting an optimum design. Therefore, for the design of HEs
advanced optimization techniques are preferred. The review work on parametric design optimization was not attempted previ-
ously by taking into consideration various types of HEs therefore this review paper may turn into the complete information
at one place and it may be very useful to the industrial design and successive researchers to choose the direction of their
research work in the field of parameter optimization of HEs using advanced optimization algorithm.
1 Introduction
A heat exchanger (HE) is a device which is used for recover-
ing the thermal energy between two or more fluids kept at
different temperature. Various types of heat exchangers are
available in the industry i.e. shell-and-tube heat exchang-
ers (STHE), plate-fin heat exchangers (PFHE), fin-and-
tube heat exchanger (FTHE), gasket heat exchanger, and
various configurations of heat exchanger networks (HENs)
etc. The design of these HEs is based on various geomet-
ric and operational parameters while meeting with certain
specified objective(s) such as minimum total cost, maxi-
mum heat transfer rate, minimized weight etc. with certain
specified constraint(s) such as constrained associated with
maximum pressure drop, minimum and maximum fluid flow
velocity, structural constraint etc. These HEs are used in
various industries as process equipment e.g. heats recovery,
refrigeration, cryogenics, food processing and many other
industries.
PFHEs and STHEs are the widely used heat exchangers
for industrial and as well as commercial applications. The
STHE is the HE in which on fluid is carried by tube and the
other fluid is carried by shell. The heat transfer takes place
by mean mutual heat transfer between the tube and shell side
fluid. The design of STHE depends upon many geometrical
parameters i.e. shell diameter, tube diameter, number tubes,
baffle spacing, number of tube passes, tube length, tube lay-
out etc. and operational parameters i.e. specification of heat
pump, fluid flow velocity inside the tube and shell, fouling
resistance etc. PFHEs are the HE in which transfer of heat
takes place between two fluids by means of plates and finned
chambers. The design of PFHE depends upon many struc-
tural parameters i.e. fin height, length and thickness, length
of fluids flow, no flow length, number of fins, fin frequency
etc. and many operational parameters. Similarly, the design
of other HEs depends upon many structural and operational
parameters.
The HENs design uses a detailed analysis for the opti-
mum design of heat exchangers. It employs three concepts:
