Abstract Estimation of thermal contact conductance between two dissimilar metal
rods for 1D transient heat conduction problem is carried out by inverse heat transfer
using Jaya algorithm. Aluminum and brass are chosen as rod materials. Jaya is a
simple and efficient algorithm in which the results achieved for a particular problem
should move toward the best solution. Various cases like different population size,
different profiles of contact conductance, and different errors in temperature measurements are considered. Jaya excellently estimates all profiles and is found to be a
promising algorithm for other inverse heat transfer problems.
Keywords Thermal contact conductance · Inverse heat transfer · Jaya algorithm
1 Introduction
Generally, when two cylindrical rods are pressed against each other, a perfect contact
is assumed at the interface. However, no surface is perfectly smooth, and the contact
is between the peaks and valleys of the two mating surfaces of rods. The heat transfers
through peaks take place due to conduction, and the valleys form air pockets offering
some resistance as air acts as an insulation. This leads to temperature drop at the
interface of two layers [1]. The interface conductance plays a vital role in the design
of various engineering systems that are concerned with flow of heat, like valve
and seal of IC engine, heat exchangers, and many other applications. The use of
inverse methodology in this field is conducted to avoid the various problems faced
in estimating the interface conductance using experimentation. There has been lot
of work available in estimation of contact conductance by experimental approach
