For melting simulation, solid-liquid coupling, liquid-gas interaction, bubble/foam generation, etc., many new methods have been emerging in recent years in computer graphics. To further push advance the technical frontier of the aforementioned phenomena, our novel solution is to focus on an efficient heatbased method towards faithful simulation of physical procedures pertinent to phase transiti...

In this preliminary scoping study, post-accident temperature transients of several fusion-fission designs utilizing ITER-FEAT-like parameters and fission pebble bed fuel technology are examined using a 1-D cylindrical Matlab heat transfer code along with conventional fission decay heat approximations. Scenarios studied include systems with no additional passive safety features to systems with m...

A boundary element formulation for the solution of multiple moving boundary problems is presented and tested herein. A heat transfer problem involving heating of solid, melting of solid and vaporisation of liquid is considered. Numerical results show that the boundary element method is more suitable and more accurate than both finite difference and finite element methods for this kind of problems

in this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(v/v) percent of the reports. the overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

Standard melting point analyses only partially describe the thermal properties of eusocial beeswaxes. Differential scanning calorimetry (DSC) revealed that thermal phase changes in wax are initiated at substantially lower temperatures than visually observed melting points. Instead of a sharp, single endothermic peak at the published melting point of 64 degrees C, DSC analysis of Apis mellifera ...

Recent developments in synchrotron brilliance and X-ray optics are pushing the flux density in nanofocusing experiments to unprecedented levels, which increases the risk of different types of radiation damage. The effect of X-ray induced sample heating has been investigated using time-resolved and steady-state three-dimensional finite-element modelling of representative nanostructures. Simulati...

In this study, thermal and heat transfer characteristics of nano based PCM during energy storage and release processes were investigated. This work also presented the preparation of nanofluid, which is solid-liquid composite material consisting of TiO2 nanoparticles (NPs) embedded into melting palmitic acid. Size of the TiO2 nanoparticles synthesized by sol-gel method was measured by using tran...
