Cascaded thermal storage, consisting of multiple Phase Change Materials (PCMs) with different melting temperatures, has been proposed to solve the problem of poor heat transfer caused by unavoidable decrease of temperature differences during heat exchange process. This paper conducts a theoretical study of the overall thermal performance for a cascaded thermal storage system. Both heat transfer...

The general context of this work concerns the latent heat storage (cold storage) by encapsulated spherical nodules of 7.7 cm in diameter containing a Phase Change Material (PCM) and filling a cylindrical tank (about 2500 nodules per m3). During the storage process, a cold heat transfer liquid flows through the tank to crystallize the PCM inside the nodules. The stored energy is released when a ...

The melting of a particle-laden slurry in a cylinder is investigated. The slurry consists of neutrally buoyant ceramic hollow spheres suspended in a paraffin wax. Melt front propagation and heat transfer processes during phase change in this particle-laden material is studied. The numerical analysis employs a particle-diffusive model and the enthalpy method. Experiments are carried out to valid...

In this paper, we investigated the influence of melting on mixed convection heat and mass transfer from the vertical flat plate in a non-Newtonian nanofluid saturated porous medium. The wall and the ambient medium are maintained at constant, but different, levels of temperature and concentration. The Ostwald–de Waele power-law model is used to characterize the non-Newtonian nanofluid behavior. ...

Dendritic solidification is a common mode of solidification. It is also an important model problem in non-equilibrium physics and pattern formation physics. Current theories couple the transfer of latent heat with selection mechanisms at the interface. Measurements of succinonitrile (SCN) dendrites in microgravity show reasonable agreement between heat transfer predictions and experiment. Howev...

The present paper emphasizes the potentialities of the industrial use of three-dimensional mathematical modelling of glass melting tanks for optimization of working conditions, design and control of indusaial furnaces. A short review of related recent relevant works is presented and industrial needs and requirements in modelling are discussed. A modelling procedure to solve the heat and mass tr...

Hydronic or electric heating of pavement surfaces has been used in the prevention of ice formation and snow deposition with the aim of improving transportation safety. This paper describes a numerical model of a heated pavement and the snow melting processes occurring on its surface. A set of boundary conditions have been defined, and models of heat and mass transfer developed, that allow treat...

An experimental as well as numerical investigation was conducted on the melting/solidification processes of a stationary phase change material (PCM) in a shell around a finned-tube heat exchanger system. The PCM was stored in the horizontal annular space between a shell and finned-tube where distilled water was employed as the heat transfer fluid (HTF). The focus of this study was on the behavi...

We present a simple, linear 3D cellular automata approach for animating the melting process of solid volumetric models. Accurate modelling of object melting usually requires complicated physical simulations of heat transfer and phase transition from solid to liquid. Instead, we propose a simplified model to describe the melting behaviors of highly viscous objects, such as wax, lava, plastic, me...
