Use Of Experimentation In The Accurate
Numerical Simulation Of Thermal Processes

Abstract
Experimental results play a crucial role in the validation of mathematical and
numerical models for a variety of thermal transport problems. Material properties
that are crucial to any accurate simulation are obtained experimentally. In
addition, there are many important processes where the boundary conditions are
not well defined. However, experimental work can be used to provide the
appropriate boundary conditions, or the numerical solution of a coupled inverse
problem can be used to define these for an accurate simulation. Finally, there are
many problems in which numerical simulation is particularly suitable over given
parametric ranges, while experimentation is more appropriate over other regions.
In such cases, a concurrent numerical and experimental approach may be used to
solve the problem more accurately and efficiently. The basic considerations that
arise in these approaches are outlined. A few circumstances, where a coupling of
the experimentation with the simulation is appropriate, or where experimentation
is used to define the boundary conditions are presented.
Keywords: numerical simulation, thermal processes, systems, experimentation.
1 Introduction
Numerical modeling and simulation of basic and applied problems is extensively
used in thermal systems to understand the underlying phenomena and design and
optimize the system. Numerical simulation is of crucial importance because of
the limited applicability of analytical methods, particularly for practical
applications which are generally quite complicated, and the expense and time
involved in experimental methods, see Jaluria [1]. The model is often validated
by the use of analytical and experimental results, if available. Experimental
