| description | The aim of this study is to obtain the heat transfer characteristics of the
heated tube inline and staggered arranged immersed in the thermal energy
storage material (paraffin wax) as phase change material (PCM). The
information about thermo-physical properties of phase change thermal
storage material and heat transfer characteristic is very important for
designing of thermal energy storage system. The Differential Scanning
Calorymetery (DSC), density meter, thermal conductivity meter, and
viscometer are used for measuring the thermo-physical properties of thermal
energy storage material (paraffin wax).
Analysis of the heat transfer characteristics of heated tube inline and
staggered arrangement immersed in the thermal energy storage material by
experimental and numerical were used. These results would be helpful in developing analyses and in their verification to design thermal energy storage
system.
This study also presents an efficient and adequate of numerical technique for
solving transient heat transfer problem of melting processes and then
compare to the experimental result. The proposed technique comprises
between the specific heat capacity and conduction/convection is heat transfer
modes for solved the problem by a finite difference scheme. The temporal
heat storage and the movement rate of solid-liquid interface in paraffin wax
as phases change material (PCM) heated tube inline and staggered
arrangement are studied.
Numerical scheme is suitable for solving phase change problem with
boundary condition of constant heat flux. The result scheme is efficient and
adequate. The numerical results agree fairly well with the experimental
results, which show that the model is accurate enough to predict the solid
PCM melting rate and the time needed to the melt of the solid PCM. The
model also can be used to optimize the design and operation of thermal
energy storage system with PCM outside the inline and staggered heated
tube arrangement. |
