1. Phase Equilibrium-aided Design of Phase Change Materials from Blends : For Thermal Energy Storage
Abstract : 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. READ MORE

2. Heat Transfer Aspects of Using Phase Change Material in Thermal Energy Storage Applications
Abstract : Innovative methods for providing sustainable heating and cooling through thermal energy storage (TES) have gained increasing attention as heating and cooling demands in the built environment continue to climb. As energy prices continue to soar and systems reach their maximal capacity, there is an urgent need for alternatives to alleviate peak energy use. READ MORE

3. Phase change with stress effects and flow
Abstract : In this thesis two kinds of phase change i.e., solid state phase transformation in steels and solid-to-liquid phase transformation in paraffin, have been modeled and numerically simulated. READ MORE

4. Environmental, health and safety assessment of phase-change solvents for post combustion CO2 capture
Abstract : A novel class of solvents exhibiting liquid-liquid phase separation upon reaction with CO2 and/or change in temperature, promises significant reduction of energy requirement of the post combustion capture by chemical absorption. However, proceeding to a large-scale application of novel materials requires holistic evaluation of the aspects related to human health, safety, and environmental impacts currently missing for phase-change solvent alternatives.

5. On the Design Considerations for Thermal Energy Storage with Phase Change Materials: Material Characterization and Modelling
Abstract : Integrating thermal energy storage (TES) technologies to a process enables storing and releasing thermal energy on demand. Depending on the implementation, this may lead to economic and ecological improvements, e.g. by shifting the peak demand to off-peak hours or by increasing the share of utilized renewable energy.
