Microphysiological systems (MPS) combine microfluidics, MEMS, and biotechnology techniques to mimic human organ function in vitro. Such devices are being developed to provide better levels of tissue and organ functionality compared with conventional cell culture systems, and have great ... En savoir plus

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... En savoir plus

Introducing heat to the formation has proven to be an effective way of lowering the oil viscosity of heavy oils by raising the temperature in the formation. The application of electrical energy has gained more interest during the last decade because it offers fewer restrictions for its ... En savoir plus

Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, ... En savoir plus

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The ... En savoir plus

Resin Transfer Molding (RTM), is a closed mold reinforced polymer composite molding process where the resin is infused under a pressure gradient. The liquid resin is infused through the dry preform and displaces air to saturate the preform. One of the governing parameters in an RTM ... En savoir plus

We have chosen droplet-based microfluidics as a platform for single cell analysis using the encapsulation technique. For this, we study the water in oil droplets formation inside a 2D microfluidic flow focusing geometry designed. We have performed Computational Fluid Dynamics (CFD) ... En savoir plus

Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus

In this work we tackle a more theoretical aspect of micro-injection molding, to better understand physics during the process, through numerical simulations of cavity filling. We developed a two phase flow approach by the use of COMSOL Multiphysics®. In a first step, a Level Set model is ... En savoir plus

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... En savoir plus
