Water management on proton exchange membrane fuel cells is one of the biggest issues that stop the effective commercialization of this promising technology. Due to water flooding, the performance of fuel cells decays rapidly at high current densities. To better design fuel cell electrodes, a...

Parabolic partial differential equations (PDEs) are used as models of transport-reaction phenomena in a variety of different industrial chemical and materials engineering processes, and can yield precise descriptions of process variables with complex temporal and spatially dependent system...

Pulses of ocean primary productivity during the fall season are frequent in the mid-latitudes when ocean cooling and wind-driven turbulence erode the surface stratification and allow the injection of nutrients into the euphotic zone. This phenomenon is often referred to as a phytoplankton fall...

Consider an open control volume consisting of a porous medium submerged in a surrounding ambient fluid of density ρa. The top and bottom of the control volume allow ambient fluid to enter the porous medium. Saline fluid of density ρs>ρa is supplied at a constant rate of Qo near the top of the...

Complex concentrated slurry flows in horizontal pipelines are widely seen in many industries for transportation of solid particles or process wastes. i.e., tailings. Slurry flows can occur in a turbulent regime, and the carrier fluid usually shows a non–Newtonian behavior. Understanding the flow...

This work is devoted to the CFD analysis of multiphase flow using Euler-Euler model. In particular, Euler-Euler multiphase model is applied to study numerically the behaviour of gas-solid system and solid-liquid system. The main objective of this work is to validate Euler-Euler multiphase model...

Thunderstorms have the potential to produce severe weather and can result in significant financial and human losses. The province of Alberta is one of Canada’s most active thunderstorm regions, with the record for insured damage due to hail. Therefore, it is crucial that thunderstorm forecasts be...

The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...

Au, Ag, Hg, many other metals, diamond, coal, oil and tar sands are extracted by flotation process. We can define flotation as a single, most significant unit operation in mineral processing, used in extraction of all kinds of minerals. A study of air bubble dynamics and gas-liquid multiphase...

Monitoring and understanding of Labrador Current variability is important because it is intimately linked to the meridional overturning circulation and the marine ecosystem off northeast North America. Nevertheless, knowledge of its decadal variability is inadequate because of scarcity of current...
