Temperature of an Externally Heated Metallic Microparticle in a Phase Change Material
Phase change materials (PCMs) play a significant role in the field of thermal energy storage. The strength of PCM stems from their ability to keep a large amount of energy in a small temperature difference. In this study, ...
Solar image characteristics of solar concentrators
Solar beams can be concentrated by various optical systems in order to obtain energy at high temperatures. Among the various concentration devices the main criteria for classification deal with the optical systems used. ...
Melting within a spherical enclosure
The problem considered is that of the melting of a phase change material, initially at its saturation temperature, which is enclosed within a spherical shell whose surface temperature is suddenly raised to some fixed value. ...
Onset of convection in fluid layers with nonuniform volumetric energy sources
The thermal stability of a fluid layer with nonuniform distribution of the volumetric energy sources is studied. The conditions leading to the onset of convective motions in the fluid are determined analytically by linear ...
