Thermal enhanced oil recovery methods form the majority of the enhanced oil recovery projects worldwide. Among the thermal methods, steam injection is the most effective and most applied process in petroleum industry. The main mechanism of the steam injection method is the reduction of ...

Joule-Thomson effect describes a change of temperature in a fluid due to a sudden change of pressure under adiabatic conditions. The aim of this study is to reproduce Joule-Thomson effect when an incompressible gas flows through a narrow pipe connecting two tanks at different pressures. ... En savoir plus
An auto-consistent multiphysical 3D model with strong coupling between Heat Transfer, Navier Stokes and ALE problems is proposed for the description of transient development of the keyhole and the melted zone in laser welding of metallic materials. It showed a satisfactory correspondence ... En savoir plus
A lateral observation of laser-induced keyhole through the quartz window is an easy and cheap experimental method. It opens an interesting perspective for the study of keyhole asymmetry in case of dissimilar metal combinations. To quantify the effect of quartz window on the observed ... En savoir plus
The well-known Moore’s ‘Law’ sets a target for the down-scaling of silicon-based electronic devices. The down-scaling of devices may provide better performances, such as increased speed and lower power consumption that lead to a lower cost per bit. This is true for the processor ... En savoir plus
COMSOL Multiphysics® is being utilised to develop Thermal Model for Directed Energy Deposition (DED) process with an objective to analyse the heat transfer phenomenon during and after the process. With the rapid growth of industrial acceptance of DED process, different research ... En savoir plus
In the design, manufacture, assembly and installation of transformers some of the important requirements are; protection of the environment, operational safety, minimizing maintenance requirements and the risk of fire. Oil insulated transformers have some limitations such as; low ... En savoir plus
The heat transfer rate and borehole design represent great challenges to thermal equipment designer of the ground-coupled heat pump. The present model represents a mathematical numerical technique implemented to tackle such problem. A thermal assessment was established to estimate the ... En savoir plus
Seawater can be converted into fresh water using solar energy. This is as an easy, suitable and green solution method to obtain heat for desalination. It is possible to concentrate the sunlight heat flux onto a small focal area by using a Fresnel lens. When the focal area is correctly ... En savoir plus
Heat cancer therapy (HT) involves increasing tumor temperatures to 40-44°C and is a potent radiosensitizer for the treatment of solid tumors, including brain cancer. Current strategies to heat deep-seated targets in the brain are primarily invasive, and existing HT applicators do not ... En savoir plus
