In this paper, 3-dimensional geometric models have been developed to evaluate the particle distribution effect on the thermal performance of a composite high conductivity laminated MEPCM board. For the purpose of comparison three geometric configurations (rectangular, triangular and pyramidal)...

The use of latent heat storage, microencapsulated phase change materials (MEPCMs), is one of the most efficient ways of storing thermal energy and it has received a growing attention in the past decade. However, there is no complete overview of its utilization in thermal energy storage systems,...

This paper discusses physical process of thermal transfer in energy pile foundations, which function as structural support for the buildings as well as heat exchangers serving energy to the buildings. Derivation of conservation of energy balance is presented, depends on its type of heat transfer...

The paper presents an analysis of thermodynamic losses in thermal reservoirs due to irreversible heat transfer and frictional effects. The focus is upon applications to large-scale electricity storage for which it is the loss in availability (or exergy) that is most relevant. Accordingly,...

This paper investigates the transient heat conduction around the buried spiral coils which could be applied in the ground-coupled heat pump systems with the pile foundation as a geothermal heat exchanger. A transient ring-coil heat source model is developed, and the explicit analytical solutions...

Recently, oxy-fuel combustion has received increasing attention as one of the short-term solutions for capturing CO2 from power plants. Despite their quick development, there are several issues that need further research. Combustion characteristics, heat transfer, emissions levels, optimum...

Solar energy is one of the most efficient, clean and affordable energy alternatives available today. With the current concerns about global warming and ever increasing energy rates, countries are seriously looking for domestic and industrial usage of solar energy. In the present study, a detail...

In view of above present investigation is planned with the following.

The longitudinal fluid flow and heat transfer between an elliptical hollow fiber membrane tube bank (EHFMTB) used for air humidification are investigated. In the tube bank, the water stream flows inside the fibers, while the air stream flows axially between the fibers. The air and the water...

This paper studied the annual thermal performance of a photovoltaic wall (PV wall) mounted on a multi-layer façade. Based on some developed unsteady-state heat transfer models for a PV wall and a normal wall, the annual thermal performance of two types of walls was simulated. Compared with a...
