An effectiveness-NTU technique for characterising a finned tubes PCM system using a CFD model
Tay, N. H. Steven; Belusko, Martin; Castell, Albert; Cabeza, Luisa F.; Bruno, Frank (Elsevier, 2014)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 ... -
Computational efficiency in numerical modeling of high temperature latent heat storage: comparison of selected software tools based on experimental data
Pointner, Harald; Gracia Cuesta, Alvaro de; Vogel, Julian; Tay, N. H. Steven; Liu, Ming; Johnson, Maike; Cabeza, Luisa F. (Elsevier, 2016)In this article, four different numerical models for the investigation of phase change processes within latent heat storage are described and compared concerning accuracy, convergence behavior and computational efficiency. ... -
Experimental investigation of the effect of dynamic melting in a cylindrical shell-and-tube heat exchanger using water as PCM
Gasia, Jaume; Tay, N. H. 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 ... -
Numerical study of dynamic melting enhancement in a latent heat thermal energy storage system
Gasia, Jaume; Groulx, Dominic; Tay, N. H. Steven; Cabeza, Luisa F. (Elsevier, 2020)In the present work, a 2D Cartesian numerical model is implemented to simulate the transient behaviour of a latent heat thermal energy storage system under the effect of the dynamic melting enhancement technique. This ...
