We present a novel approach to fluid simulation, allowing us to take into account the surface energy in a precise manner. This new approach combines a novel, topology-adaptive approach to deformable interface tracking, called the deformable simplicial complexes method (DSC) with an optimization-based, linear finite element method for solving the incompressible Euler equations. The deformable si...

From the student feedback questionnaire, some students opined that the concepts of fluid mechanics are quite abstract and that they have difficulty in grasping the phenomena in real life situation. Hence, it demands some innovative learning methodologies to help arouse their interest. This paper depicts the development and implementation of an interactive teaching package on learning of basic f...

Simulations of viscoplastic materials are traditionally governed by continuum mechanics. The viscous behavior is typically modeled as an internal force, defined by diverse quantities. This work introduces a fluid model to simulate the viscoplastic effect of solid materials, such as plastic, wax, clay and polymer. Our method consists in modeling a solid object through a non-Newtonian fluid with ...

This work aims at generating a model of the ocean surface and its motion from one or more video cameras. The idea is to model wave patterns from video as a first step towards a larger system of photogrammetric monitoring of marine conditions for use in offshore oil drilling platforms. The first part of the proposed approach consists in reducing the dimensionality of sensor data made up of the m...

A jet-type magnetically driven fluid micropump to drive conductive fluids has been designed, fabricated, and tested. The pump actuation is based on a rotary magnetic micromotor with fully integrated stator and coils operating with the rotor immersed in the fluid to be pumped, thereby driving the fluid from a inlet flow reservoir through integrated flow channels to an outlet flow reservoir. The ...

Graphical Processing Units (GPUs) are massive floatingpoint stream processors, and through the recent development of tools such as CUDA and OpenCL it has become possible to fully utilize them for scientific computing. We have developed an open-source CUDA-based acceleration framework for 3D Computational Fluid Dynamics (CFD) using Smoothed Particle Hydrodynamics (SPH). This paper describes the ...

This paper proposes a new approach to control a flow. Controlling a flow consists either to change its state to another state or to maintain its current state whatever external disturbances. Here the control of the laminar plane Poiseuille flow is considered. To estimate the state of this flow, existing control methods rely on a set of limited wall shear stress measurements. These existing meth...

Force feedback from remote or virtual operations is needed for numerous technologies including robotics, tele-presence, teleoperation (e.g., surgery, etc.), games and movies. To address this need, the authors are investigating the use of electrorheological fluids (ERF) for their property to change the viscosity under electrical stimulation. This property offers the capability to produce feedbac...

Aerosol particles can readily penetrate through air permeable fabrics. Air flow and aerosol deposition models were used to determine the skin deposition rates of aerosols through up to two fabric layers. These models were used in conjunction with a plume dispersion model to examine the risks associated with wearing air permeable CBR protective clothing, to inform IPE fabric development programs...

[1] Photochemically processed urban emissions were characterized at a mountain top location, free from local sources, within the Mexico City Metropolitan Area. Analysis of the Mexico City emission plume demonstrates a strong correlation between secondary organic aerosol and odd oxygen (O3 + NO2). The measured oxygenated-organic aerosol correlates with odd oxygen measurements with an apparent sl...
