An effectiveness-NTU technique for characterising a finned tubes PCM system using a CFD model
MetadataShow full item record
Numerical modelling is commonly used to design, analyse and optimise tube-in-tank phase change thermal energy storage systems with fins. A new simplified two dimensional mathematical model, based on the effectiveness-number of transfer units technique, has been developed to characterise tube-in-tank phase change material systems, with radial round fins. The model applies an empirically derived P factor which defines the proportion of the heat flow which is parallel and isothermal. This P factor was determined using a validated computational fluid dynamics model. This method can be used to design and optimise tube-in-tank salt based phase change thermal storage units with finned tubes.

Steven; Belusko, Martin; Cabeza, Luisa F.; Bruno, Frank (Elsevier, 2017)In the present paper, an experimental study is carried out to evaluate the effect of the dynamic melting concept in a cylindrical shell-and-tube heat exchanger using water as the phase change material (PCM) and a potassium ...
Embodied energy and cost of high temperature thermal energy storage systems for use with concentrated solar power plants Jacob, Rhys; Belusko, Martin; Fernández Renna, Ana Inés; Cabeza, Luisa F.; Saman, Wasim; Bruno, Frank (Elsevier, 2016)The intermittency of renewable energy systems remains one of the major hurdles preventing a large scale uptake of these technologies and concentrated solar power (CSP) systems are no different. However, CSP has the benefit ...
