A latent heat storage nanocomposite made of stearic acid (SA) and multi-walled carbon nanotube (MWCNT) is prepared for thermal energy storage application. The thermal properties of the SA/MWCNT nanocomposite are characterized by SEM (scanning electron microscopy) and DSC (differential scanning...

LED (light emitting diode) technology has been developed rapidly in recent years in the area of illumination applications. However, the rate of heat generation increases with the LED illumination intensity. The LED chip temperature is critical to determine the LED lifetime and efficiency. In...

CO2 hydrate slurry can be used in a lot of practical applications such as CO2 capture, CO2 storage-transportation and CO2 sequestration processes. However, CO2 hydrate slurry is generally formed at low temperature and high pressure. The objectives of this study are to develop new absorbents to...

Binary nanoemulsion is defined as the nanoemulsion of which base fluid is a binary mixture such as NH3/H2O solution. The objectives of this paper are to estimate the effect of nano-sized oil droplets on the performance of a diffusion absorption refrigerator (DAR) and to find the relationship...

A novel combined system that combines a MEE–ABHP (multi-effect evaporation–absorption heat pump) with a VCR (vapor-compression refrigeration) cycle is proposed to simultaneously generate cooling and fresh water. In the combined system, the condenser of the VCR system is replaced by the...

In this study, Al2O3 nanoparticles and NaCl aqueous solution are combined into Al2O3/NaCl aqueous solution nanofluids to enhance the CO2 absorption of the base fluid (NaCl aqueous solution). The absorption experiments are carried out in the bubble type absorber system. The particle concentration...

The objectives of this paper are to analyze the heat transfer characteristics during the NH3–H2O absorption process in plate heat exchangers and to develop the experimental correlations of the heat transfer coefficient for the compression/absorption hybrid heat pump application. The parametric...

The integrated gasification combined cycle (IGCC) is getting much more attention due to the rich reserves of coal around the world. In general, the absorption rate of a physical method such as the IGCC system is weaker than that of a chemical method, but it needs much less energy during the...
