Microencapsulated phase change material (MPCM) as a new thermal energy storage material and a heat transfer medium have attracted considerable attention in the thermal energy storage field. Solidification and melting models of a single PCM particle are constructed in this thesis. An effective numerical method for the problem of a spherical particle with a moving boundary was developed and validated by an iterative analytical series solution. A new liquid-solid interface model was proposed for modelling the effect of binary phase composition on the solidification of an alloy and a mixture PCM p

The present work investigates, numerically, the process of melting and solidification in hollow vertical cylinders, filled with air and phase change material (PCM). The PCM used is sodium nitrate, which expands upon melting. Therefore, a void must be present within the cylinder, which is filled with air. The influence of cylinder shape on melting time is determined. The numerical model takes both conductive and convective heat transfer into account during the melting process. The Volume-of-Fluid (VOF) model is used to track the interface between the PCM and air as the PCM melts. Three dimensio

Abstract:

During the last deglaciation (ca. 24-10 ka thousand years ago (ka)), the North American Laurentide Ice Sheet (LIS) was a major source of meltwater to the Arctic Ocean, North Atlantic Ocean, and the Gulf of Mexico (GOM), and it is hypothesized that meltwater routing played an important role in regulating Late Quaternary millennial-scale climate variability, via its influence on Atlantic Meridional Overturning Circulation (AMOC). For example, the meltwater routing hypothesis predicts that a rerouting of meltwater from the GOM to the North Atlantic and/or Arctic Oceans resulted in a decrease of N

We improved the accuracy of the capacitance calculations by increasing the overall simulation time by an order of magnitude compared to former publications and discussed possible error sources.

Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this.

Blends however do not have robust phase change unless chosen articulately. This thesis links bulk blends and robust, cost-effective PCMs via the systematic design o

In this study, (GeSbSn)100-xMx thin films (M=Ta、Fe、Ru、Ni or Co) are deposited on nature-oxidized Si wafer and glass substrates by DC magnetron co-sputtering. From the thermal analysis, we choose (GeSbSn)100-xFex and (GeSbSn)100-xCox thin films to investigated the effects of Fe or Co on the optical properties and microstructures of these films, and investigate its possibility for rewrit

碩士<br>國立成功大學<br>機械工程學系碩博士班<br>96<br>The present study considers a mixture of n-Octadecane and Al2O3 nanoparticles as a phase change nano material for the latent-heat thermal energy storage application Thermophysical properties of the PCM containing varies mass fractions of alumina particles were determined experimentally as a function of temperature. Moreover, melting heat transfer characteristics of the PCM dispersed with alumina particles were examined experimentally in a differentially heated vertical square enclosure with the relevant parameters in the ranges : Ra=1710000~5670000 ; Ste=0

Abstract:

Fundamental educational change is necessarily an outcome of authentic participation confirmed in community struggle against defined forms of oppression: this is the proposition explored in the course of the three case study experiences presented here. Similarly, the contexts, conditions and terms of participation are considered with regard to defining the character of authentic 'political' success.
