Acoustic Upside-Down Levitator with a Solid Sample

L. Holitzner [1], E. G. Lierke [2],
[1] Paul Scherrer Institut (PSI), Villigen PSI, Switzerland
[2] tec5 AG, Oberursel, Germany

Introduction: Acoustic levitators are used to levitate small samples (ca. 0.01 - 6 mm) at a stable position in a gas or liquid environment. Acoustic levitators were first developed und used for experiments in space (1970s, by NASA / ESA), the application later became terrestrial (1990s). ... Saiba Mais

Simulation of Adsorption Mechanisms of Methane and Carbon Dioxide in Shale Matrix

Multiphysics Modeling and Development of Thermoelectric Generator for Waste Heat Recovery

Asutosh Prasad [1], Raj CN Thiagarajan [1],
[1] ATOA Scientific Technologies Pvt Ltd, Bengalore, Karnataka, India

Waste heat is inevitable in any heat engine while producing useful mechanical work. A lots of heat energy is often dissipated to surrounding environment as waste, which limits the system efficiency. In almost all of the industrial processes, half of the heat energy is turned into waste ... Saiba Mais

Comprehensive Numerical Modeling of Filamentary RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... Saiba Mais

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Saiba Mais

Simulation of CVD Process in a Reactor
