Pressure projection is the single most computationally expensive step in an unsteady incompressible fluid simulation. This work demonstrates ability of data-driven methods to accelerate approximate solution Poisson equation at heart pressure projection. Geometric Multi-Grid are identified as linear convolutional encoder–decoder networks and a smoother developed using automatic differentiation o...

In conventional microfluidic devices, fluids are often confined behind solid plastic walls that restrict access and trap gas bubbles; in open microfluidics some replaced by fluid ones (i.e. interfaces with immiscible fluids). both cases, flows usually driven external pumps or gravity. An innovative technology has been developed which two-dimensional patterns of cell-culture medium standard Petr...

We propose a model of starburst–driven galactic outflows whose dynamics depends on both radiation and thermal pressure. Standard models of thermal pressure–driven winds fail to explain some key observations of outflows at low and high redshift galaxies. We discuss a scenario in which radiation pressure from massive stars in a stellar population drive a shell of gas and dust. Subsequent supernov...

Polymeric nanofbers, specifcally fabricated by electrospinning, offer viable means useful for a wide range of applications such as health, energy and environmental issues. However, among the mentioned sectors, desalination and water/wastewater treatment applications have been highlighted during the past decade. This article focuses on the present status and recent develo...
