The main aim of the study is to analyze the heat transfer through the clay brick walls of the residential building to find out the dominant mode of heat transfer and incorporate various materials in the wall to reduce heat loss and increase energy efficiency. The transient thermal analysis was performed using the finite element method, and by employing a CFD program focused on heat transfer processes. Later, two models of building wall fragments incorporating the Phase change materials were developed to identify the optimal position of the PCM layer inside the wall and to investigate the role of PCM on the heat transfer rate. Insulation was done with the different types of plywood and finite element simulation was performed to study the change in heat transfer rate. Inserting plywood into the sandwich material with Chinese plywood can reduce the heat transfer content.

Carbon nanotubes (CNTs) are one-dimensional tubular structures of carbon that have attracted much attention due to their potential to be used in various fields like energy storage/conversion devices, biosensing devices, drug delivery systems to name a few. Their excellent electrochemical properties like electron mobility, electrical and thermal conductivity, and high surface area make them good material for use in energy storage and conversion materials. The most promising research in the synthesis and applications of CNTs toward energy conversion and storage is highlighted along with limitations faced in mass production.
