Phase change material slurries (PCS) can be employed in the refrigeration and air conditioning systems as both secondary refrigerant and cold energy storage media simultaneously, which benefits not only the system efficiency improvement by the high cold carry capacity but also the reduction of...

Due to the complexity of the fluid flow and heat transfer in packed bed latent thermal energy storage (LTES) systems, many hypotheses were introduced into the previous packed bed models, which consequently influenced the accuracy and authenticity of the numerical calculation. An effective packed...

The solid-gas reaction heat transformer, which can upgrade the temperature of middle-grade heat (such as industrial waste heat, solar energy, geothermal energy, etc.) is considered promising for energy-saving in the near future. It provides high storage capacity of heat, wide range of working...

Central governments or the international community at large are concerned about subnational service delivery. The design of targeted expenditure programs features frequently in central efforts to redistribute infrastructure and social spending or assure minimum standards. These programs are...

We analyze Engel curves for nuclear households in rural China. The sample includes more than 5000 nuclear families covering nineteen out of thirty Chinese provinces. We consider expenditures on food, also subdivided into several food subcategories such as cereals, or meat and fish, and other...

Eutectic molten salt can be used as the latent thermal energy storage (LTES) medium in solar energy applications. In the present study, eutectic salt (50wt% NaNO3, 50wt% KNO3) with a melting temperature of about 220°C was employed as the PCM for the middle-temperature solar energy application,...

A new kind of functional surfaces with particular characteristics, i.e., superhydrophobic surfaces, has recently been developed and applied in many fields, such as airplane, wind turbine, electric power line, photovoltaic cell, heat exchanges, ice slurry generator, and so on. The freezing delay...

This paper is the second portion of a two-part study of the heat transfer characteristics of a shell-tube LTES (latent thermal energy storage) system. The three-dimensional model was used to investigate the discharging characteristics of the LTES system. Pure paraffin and paraffin/expanded...

This paper is the first portion of a two-part study of the heat transfer characteristics of a shell-tube latent thermal energy storage (LTES) system. A three-dimensional computational fluid dynamics model based on enthalpy method was developed to investigate the charging characteristics of the...
