The initial motivation for this work was to explore the relationship between the shape of particles and the thermal conductivity of nanofluids or nanocomposites containing them. Since the possibility for manufacturing exotically-shaped particles is ever growing, it was thought useful to devise a way to select which materials and shapes have a potential for better thermal properties. ...

This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical body (2D) or a complete manikin (3D) is modeled. The work is based on previous methods and results from ...

A new experimental device has been developed in order to characterize the phase change material (PCM) thermal properties (thermal conductivity k, sensible and latent heat thermal energy storage, cp and Lf) in the solid phase, during the solid-liquid transition and in the liquid phase. It allows to measure cylindrical samples of maximum 60 mm radius and 10 mm thick. A typical measurement consists ...

Heat management is crucial for the satisfactory operation of HT-PEM (High temperature polymer-electrolyte-membrane) fuel cells. Current work investigates the use of heat pipes in a HT PEMFC stack consisting of 24 cells, each with an active area of 300 cm^2. Heat pipes are known to be thermal superconductors operating on the principles of high convective heat transfer and phase transition. ...

This paper deals with an integrated numerical and experimental analysis work aiming at the investigation of the thermal distribution inside an industrial furnace built for metal materials treatments. The main goal of the research is to find the geometrical and/or functional parameters responsible for a not homogeneous thermal distribution inside the internal volume of the furnace. During the ...

Nowadays all branches in modern science and industry tend to solve ever complicating problems. As the result the computational time increases considerably and it become very important to reduce the processing time and use available resources more efficiently. Parallelizing problem proves itself as efficient way to overcome the described problem. In the poster we compare different methods of ...

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers for milling of drill cuttings. An F.E model of the process mill was constructed using dimensions similar to ...

Many industrial, especially heterogeneously catalysed, processes are characterised by a strong interaction between the reaction kinetics and transport phenomena. Because experiments in laboratory scale can be very time- and cost-intensive, Temkin andKul’kova developed a new reactor design for the direct testing of industrial catalysts. Based on this concept of linearly alternating catalyst and ...

β heat treatment of Uranium rods is carried out for randomization of oriented grains (called texture) developed during hot rolling or hot extrusion operation. During this process, Uranium rods undergo heating of up to 740 Deg C followed by water quenching. The objective of this work is to see the feasibility of direct heating technique for heat treatment application. At present, heat treatment ...
